The Endomembrane System

A system of interconnected membranes (also known as the cytomembrane system) that fills the cell interior and connects the cell boundary with the double membraned organelles - nucleus, plastids and mitochondria. The phospholipid bilayer forms the basis for both outer and internal membranes. Thus while the Plasma Membrane, the outer-most cell membrane is an integral component of the cell boundary, its numerous convoluted protrusions into the cell interior and its connectivity with cytomembranes also allow it to be considered a part of the endomembrane system. The endomembrane system organizes the eukaryotic cell into numerous specialized functional domains, that are recognized as different organelles.
Major endomembrane derived organelles of the plant cell are:
Endoplasmic reticulum (ER)
Golgi bodies
Outer Nuclear Envelope

Endomembrane System and Golgi Complex | Endomembrane System and Golgi Complex |

The endomembrane system is a collective term applied to all of the membranes in a cell that are either connected with or are derived from the endoplasmic reticulum (ER), including the plasma membrane but not the membranes of chloroplasts or mitochondria.

The membrane-bound organelles considered to be part of the endomembrane system are the vacuole, nuclear envelope, endoplasmic reticulum, Golgi complex, and various types of vacuoles.

Some components of the endomembrane system have direct, permanent connections with the endomembrane system (such as between the endoplasmic reticulum and the nuclear envelope), whereas other components share membrane and contents by trafficking vesicles (membrane-bound packages) from one component to another (for example, the ER sends numerous vesicles to the Golgi complex) across the…...

...trains the heart to pump more blood per stroke. Exercise also trains the muscles to use oxygen more efficiently, taking even more stress off the heart. A resting heart rate above gender averages could mean that the heart is weak or that the body is not using oxygen efficiently. The results were reliable because all scientific procedures were followed during the experimentations. Better still, a well improved result would been attained if factors that could affect pulse rate such as age, sex temperature were considered, for instance considering different age groups and also both male and female sexes.

Conclusion I’ve learned that the key is homeostasis means “staying the same”. This is valuable. Our body temperature is an important factor to our being. This is the key to remaining healthy. Our receptors monitor the environment. The control center formulates the response. Nerve impulses are output and then effectors then carry out the change. Our body has a natural sense to stay warm. In turn, our body also knows how to react to its environment. This is the cycle. Reference: Ireland, K. A. (2012). Visualizing human biology (4th ed.). Danvers, MA: Wiley....

...The coconut palm (Cocos nucifera) is a member of the Arecaceae family also known as the palm family. According to UCC Biology Department, “The spelling cocoanut is an archaic form of the word. The term is derived from 16th-century Portuguese and Spanish coco, meaning "head" or "skull". Coconut can be dated back to the story of Sinbad the Sailor, One Thousand and One Nights. He is known to have bought and sold coconuts during his fifth voyage. Its Malayalam name, Tenga, was used in the complete description of coconut found in Itinerario by Ludovico di Varthema published in 1510. Even earlier, it was called nux indica, a name used by Marco Polo in 1280. The origin of the coconut plant is to be discussed because no one really knows. O.F. Cook was one of the first modern researchers to draw conclusions about the location of the origin of Cocos nucifera based on its current-day worldwide supply. He predicted the coconut originated in the Americas, based on the fact that American coconut populations dominated the European connection. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. According to author VanZile, J (2014), “Cocos nuciferas are large palms that can grow up to 30 m (98 ft.) tall, with pinnate leaves 4–6 m (13–20 ft.) long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth.” Coconuts are categorized into two general types: tall and......

...Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.[1] Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent fields. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition. Subdisciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: Biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions among biological molecules; botany studies the biology of plants; cellular biology examines the basic building-block of all life, the cell; physiology examines the physical and chemical functions of tissues, organs, and organ systems of an organism; evolutionary biology examines the processes that produced the diversity of life; and ecology examines how organisms interact in their environment.

...Biological psychology also explores questions of how the brain itself is connected to consciousness. Basically, this branch of psychology emphasizes the goal of relating biology to the issue of psychology. It is sometimes also called psychobiology, biopsychology, physiological psychology or behavioral neuroscience. Brain functioning is the main areas of focus for biological psychology. By studying the brain, biological psychologists attempt to answer questions such the best way to help with recovery after brain damage, or what specific part of the brain helps us learn language or is involved in storing memories. They might also study what biological factors make people more likely to be affected with psychological disorders. Biological psychology has its roots in scientific and philosophical traditions from as early as the 18th and 19th centuries. For example, Rene Descartes (1596-1650) suggested that there was a specific part in the brain (the pineal gland) that connected the body with the mind. Although this was not correct, it did introduce the idea of studying specific parts of the physical brain when trying to explain the roots of behavior. (Robinson, 1995) In 1890, XXXXXXX XXXXX published The Principles of Psychology, which made the claim that the scientific study of psychology should be rooted in biology. As a science, biological psychology can be traced back to studies of anatomy (specifically neuroanatomy). By performing experiments on living creatures,......

These sub-theories require continued elaboration, particularly in light of molecular biology, to answer openended questions concerning the mechanisms of evolution in all five kingdoms of life. Introduction Physicists and chemists investigate the properties and interactions of objects, such as electrons, photons, and atoms, which are physically uniform and invariant in their characteristic traits and behavior. Accordingly, a single experiment adducing the properties of a single entity (e.g., electron or proton) can be used to extrapolate the properties of all comparable entities in the universe. In biology, the “science of the living world,” both past and present (Mayr 1997), the......

...Biology Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics. These characteristics include cellular organization, METABOLISM, response to stimuli, development and growth, and reproduction. Furthermore, the information needed to control the expression of such characteristics is contained within each organism. FUNDAMENTAL DISCIPLINES Life is divided into many levels of organization--atoms, molecules, cells, tissues, organs, organ systems, organisms, and populations. The basic disciplines of biology may study life at one or more of these levels. Taxonomy attempts to arrange organisms in natural groups based on common features. It is concerned with the identification, naming, and classification of organisms. The seven major taxonomic categories, or taxa, used in classification are kingdom, phylum, class, order, family, genus, and species. Early systems used only two kingdoms, plant and animal, whereas most modern systems use five: MONERA (BACTERIA and BLUE-GREEN......
