Cell Reproduction The term cell reproduction refers to the process of a cell splitting to form two similar cells; this is known as cell division. Eukaryotic cells reproduce by mitosis or meiosis; and prokaryotic cells use binary fission as a means of cell reproduction. (Simon,Reece,Dickey.(2010)) Mitosis is defined as a process of asexual reproduction in which the parent cell divides in two producing a replica, with an equal number of chromosomes in a haploid cell. The product of mitosis is two diploid daughter cells. The process of mitosis creates everything accept sex cells; and occurs in all organisms. The steps of mitosis are Interphase, Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. In the prophase step of mitosis the chromosomes duplicate into two sister chromatids. In metaphase the chromosomes align in the center of the cell, the spindle microtubes attach to the two sister chromatids are pulled toward the opposite poles of the cell. In anaphase the two sister chromatids separate and are considered full daughter chromosome; the mirotubes push toward opposite poles cause the cell to elongate. In telophase the chromosomes are at the far point of the opposite poles of the cell; the nucleus separates into two separate but identical daughter nuclei. In the final stage cytokinesis the cytoplasm divides forming two separate but genetically identical daughter cells. (Simon,Reece,Dickey.(2010)) Meiosis is a process of sexual reproduction which creates sex cells only either female egg cells or male sperm cells which are later combined to form a cell which receives half of its genetic makeup from two parent cells. The steps of meiosis are Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and Telophase II. In meiosis the number of chromosomes is reduced by half through the separation of homologous…...

...journey of fertilization begins. Edna's day; Edna has had a much longer life than Sammy because she was formed while still in the fetus of a human being. Her chances of becoming fertilized are about one in 500 million, even then a women's body only ovulates about 400 times altogether in a lifetime. Her time of ovulation is a dynamic process that takes place in the course of one or more minutes. The portion of the follicile facing the abdominal cavity ruptures fairly rapidly and the fluid filling the follicle and containing millions of cells runs out. Inside the vast number of cells is the ovum a.k.a, Edna (very valuable cargo). There Edna is surrounded by thousands of cells that provide nourishment and protection for the journey. In the meantime, the Fallopian tubes have received signals to get ready to capture this precious cargo. The finger-like projections of the fallopian tube have captured Edna, which is still surrounded by thousands of nutrient cells. Now Edna is safe inside the Fallopian tube, where she will wait rather content while she ripens, preparing herself for the meeting of Sammy (who has had quite an adventurous day himself)! Inside the fallopian tubes is where fertilization will take place. Fertilization time; Sammy has been ejaculated against the opening of the cervix, the furthest end of the vagina. His journey is about six to seven inches to the fallopian tubes but can take several hours. Sammy is a high-speed swimmer though, and the vagina has......

Assisted Reproduction

...Assisted Reproduction Richard Grogoza Grand Canyon University Ethics for Health Care Professionals HLT 312V Professor Paula Janine Duistermars March 31, 2013 Assisted Reproduction Assisted reproduction is an area that requires much thought. Who should be able to receive this assistance to who pays for it in the case of those receiving public funds. The ethical question as to whether a mother should be made to agree to “selective reduction,” or in common terms abort a fetus or fetuses in the case of multiple eggs that become fertilized needs to be addressed and answered. There are several ethical dilemmas that arise when dealing with donating eggs or sperm, as well as with surrogate pregnancies. Those in the low income bracket are susceptible to being exploited by the idea they can make money by donating their eggs. A woman willing to donate her eggs needs to be informed of the dangers associated with this process, such as; it is time consuming and requires a commitment to follow through with the process. Once the process is started the donor must give themselves daily injections of one of various medications that temporarily shut down their ovaries. These medications come with side effects that the donor may not be informed of. Ovarian hyper stimulation syndrome is another danger in which in some cases can lead to kidney failure and even death. The egg harvesting procedure is invasive surgical procedure in which there is a risk of injury to the bladder,......

...Cell Structure and Function AbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab, I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells Introduction The concept of this lab is producing a replica of an animal cell, and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell and its contents also, to explore thedifferences between prokaryotes and eukaryotes. Cell theory states that all cells reproduce new cells,while passing their genetic information. In addition, cells make up all living things, metabolize energyand that the chemical make-up of cells is similar. The objectives for this lab are to gather the materials,which include gelatin packs, plastic bags, water, Tupperware, bowls, and some small various householditems. The other objectives are preparing the gelatin as directed, gathering the household items that willserve as cell organelles, pouring the gelatin in the bag and placing the items in the plastic bags. Thenplace the cell replicas in the refrigerator for 24 hours. Results After twenty-four hours, I removed the cell replicas from the refrigerator and observed them. They didnot look exactly like I planed but they were understandable. Discussion Replicating the cell structures provides better understand the structure......

Asexual Reproduction

...Asexual reproduction Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which almost always does not involve meiosis, ploidy reduction, or fertilization. The offspring will be exact genetic copies of the parent, except in the specific case of automixis. A more stringent definition is agamogenesis which is reproduction without the fusion ofgametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea, bacteria, and protists. Many plants and fungi reproduce asexually as well. While all prokaryotes reproduce asexually (without the formation and fusion of gametes), mechanisms for lateral gene transfer such asconjugation, transformation and transduction are sometimes likened to sexual reproduction.[1] A complete lack of sexual reproduction is relatively rare among multicellular organisms, particularly animals. It is not entirely understood why the ability to reproduce sexually is so common among them. Current hypotheses [2] suggest that asexual reproduction may have short term benefits when rapid population growth is important or in stable environments, while sexual reproduction offers a net advantage by allowing more rapid generation of genetic diversity, allowing adaptation to changing environments. Developmental constraints[3] may underlie why few animals have relinquished sexual reproduction completely in their......

...JUDD’s Reproductions Variance Assignment 10/20/2010 To: Judd’s Reproductions’ CEO From: William Baker, Michael Derrig, Nicole Lapointe Terry Pikul, Brendan Sayers and Ryan Suerth Judd’s Reproduction prepares and sets standards for material and labor on each of its three products produced: chairs, tables and cabinets. (Refer to Schedule A). However, Judd’s does not have a formal process to compare actual results to the estimated standards and report the variances by product. Currently, Judd’s is not taking full advantage of the expected standards in terms of assessing price and quantity efficiency variances arising from the actual costs to highlight performance problems. After reviewing the company’s budgeted projections and comparing them to the actual cost of their products for January, a flexible budget (Schedule D) and variance analysis (Schedule B) was completed. Through this analysis, it has been determined that there are significant variances related to material price and quantity and labor rate and efficiency.

...Structures in All Eukaryotic Cells We're going to start with eukaryotic cells even though they tend to be more complex than prokaryotic. But, there is a method to our madness: you are a eukaryote and have eukaryotic cells, so we thought you might relate better. And, eukaryotic comes before prokaryotic alphabetically. Come up with whatever reasons you want for it, but eukaryotes are up first. Tough cookies. Eukaryotic Cell Structure and Function A cell is defined as eukaryotic if it has a membrane-bound nucleus. Any organism composed of eukaryotic cells is also considered a eukaryotic organism. Case in point: You. Biologists do not know of any single organism on Earth that is composed of both eukaryotic and prokaryotic cells. However, many different types of prokaryotic cells, usually bacteria, can live inside larger eukaryotic organisms. Creepy, but true. We humans, for example, have trillions of bacteria living in our colons, not to mention in our mouths and stomachs and small intestines and…you get the picture. Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. Deal with it. This means that all human cells, including those found in the brain, the heart, the muscles, and so on, are also eukaryotic. Here is what one of these little guys looks like: OK, we are slightly impressed. That is a lot of stuff jam-packed into something we can't see too well with the naked eye. All......

...www.asbiology101.wordpress.com An introduction to the microscope and magnification MAGNIFICATION AND RESOLUTION Because cells are too small to be seen with the naked eye, the light microscope was developed to produce enlarged and more detailed images of cells. The magnification of an image is how much bigger it appears under the microscope than it is in real life, and is worked out using the following formula: magnification = image size ÷ actual size unit metre decimetre centimetre millimetre micrometre nanometre picometre symbol m dm cm mm μm nm pm metres 1 0.1 0.01 0.001 0.000 001 0.000 000 001 0.000 000 000 01 However, magnification on its own does not increase the level of detail seen, it just increases the size. The term resolution refers to the ability to see two distinct points separately. For example, if the resolution of a light microscope is 200nm (0.2μm), this means it can see any two different points as separate objects if they are 200nm apart or more; but if they are any closer than this amount, they appear as one object. THE LIGHT MICROSCOPE Light microscopes use a number of lenses to produce an image that can be viewed directly at the eyepiece. Light passes from a bulb under the stage, through a condenser lens and then through the specimen. This beam of light is passed through an objective lens and then the eyepiece lens. The light microscope usually has a number of objective lenses which can be rotated into......

Cell Reproduction

...Cell Reproduction Introduction Cellular reproduction is the process by which cells duplicate their contents and then divide to yield two cells with similar, if not duplicate contents. Life as we know it depends on the ability of cells to store, retrieve and translate the genetic instructions required to make and maintain a living organism. In this assignment, I will discuss two different types of cell reproduction, mitosis and meiosis and, include the different stages required in order for the reproduction to take place. Mitosis Mitosis is a process by which a cell divides to form two daughter cells and produces an almost carbon copy of the parent cell. The daughter cells will consist of the same number and type of chromosomes as the parent cell and will be identical to each other. Although cell division is the defining characteristic of mitosis, a number of events must take place during mitosis prior to the splitting of the cell. There are four phases that constitute the period in which cells make preparation for cell division. The four phases are prophase, metaphase, anaphase and telophase. Prophase, the first stage of mitosis during which the chromosomes become shorter, thicker and consist of two chromatids. At this time, the chromosomes are still enclosed in the cell nucleus within the nuclear envelope. The chromosomes also contain a centromere, which is necessary in later phases for attachment to microtubules for migration. Late in prophase,......

Cell Reproduction

...WHAT IS CELL REPRODUCTION AND WHY IT HAPPENS According to our text book, Essentials of Biology, we begin life as a single cell but over the period of several months, we become a collection of trillions of cells. This process continues as we grow up and as we reach a fully mature adult age, old cells are replaced with new ones. Many cells divide at least once during their short life span and some divide many times before they die. This is known as cell division (parent cells and daughter cells) which are given the names of binary fission, meiosis and mitosis. New red blood cells, skin cells and digestive track cells are also generated. Reproduction is also how organisms are able to reproduce through meiosis which involves the replication of DNA and the splitting of molecules. Mitosis involves the cell division which produces two of the same identical cells from one single cell and happens as a result of a process that cells go through to form to nuclei with each of the nuclei containing the same number of chromosomes. Many eukaryotic organisms use this process for reproduction. Cells go though many cycles but all of the cycles happen in a specific event, some of which I partially mentioned above. The first in the Interphase cycle which is time it takes for a cell to perform its normal functions, depending on where it is in the human body. The next stage is the M state which includes both the division of the nucleus and the division of the cytoplasm—this is......

Basic Processes of Reproduction

...Basic Processes of Reproduction Bacteria: Bacteria reproduce asexually, under positive environment settings this process is carried out through the method binary fission, where the most bacterial reproduction occurs in prokaryotic cells. The second method is through mitosis in eukaryotic cells except gametes (Pruitt & Underwood, 2006). Binary fission is asexual by nature and involves the splitting of the parent cells into two equal parts which once the split can be capable of independent existence (MediLexicon, 2004-2011). Grasshopper: Grasshoppers sexually reproduce when the male grasshopper introduces his spermatozoa through his aedeagus (reproductive organ) into the females ovipositor. The sperm sack contains a large packet of proteins known as spermatophylax that helps keep the eggs properly nourished (New World Encyclopedia, 2008). Once fertilized the female lays the eggs with her ovipositor and stomach one to two inches underground to keep them protected during the winter months until they hatch in warmer weather (New World Encyclopedia). Fish: Fish reproduce is, based on the location, time of year, and the presence of a proper mate (Pruitt & Underwood, 2006). Depending on the type of fish they gather in huge schools, and females expel eggs and the males follow behind discharging Milt (sperm) into the water. Some of the eggs float some sink to the bottom, and others are, laid in nests. Once the eggs are laid, they are commonly...
