Side By Side Endoplasmic Reticulum
2,193 words... e detoxification processes by which enzymes act on chemicals and drugs to change their structure and reduce their toxicity. The smooth endoplasmic reticulum of skeletal muscle stores calcium ions that function in muscle contraction. The Golgi apparatus is composed of flattened membranous sacs, containing cisternae, that are stacked on each other like dinner plates. The Golgi apparatus modifies, packages, and distributes proteins and lipids manufactured by the rough and smooth endoplasmic ret...

Endoplasmic Reticulum Organic Molecules
1,136 words... m is used to breakdown glycogen to glucose. The endoplasmic reticulum is versatile and grows and shrinks according to the cell's activities. Chloroplasts which are found in plant cells are used in the process of photosynthesis. They fall into the category of plastids but they are differentiated in that they contain chlorophyll. These organelles produce chemical reactions from the energy that the sun gives them. The Golgi complex's structure is made up of many flattened membranes sacs that ar...

Plasma Membrane Permeable Membrane
777 wordsThe plasma membrane is the boundary of life; this selectively permeable membrane allows the cell to maintain a unique internal environment and to control the movement of materials into and out of the cell. The phospholipid bilayer (fluid music model) with specific membrane proteins accounts for he selective permeability of the membrane and passive and active transport mechanisms. Membrane phospholipids are amphipathic. Cell membranes are phospholipid bilayers with the hydrophobic hydrocarbon tai...

Plasma Membrane Passive Transport
834 wordsBeing one of the most important components of a cell, the plasma membrane, or cell membrane plays a huge role in regulating how things get in and out of cells. The plasma membranes unique structure enables it to let only certain molecules pass through the cell. This ability is called selective permeability. Most of the plasma membrane in most cells is made up of a phospholipid bilayer with proteins either embedded into it or sticking out from either side of the membrane. The heads of the phospho...

White Blood Cells Endoplasmic Reticulum
1,733 wordsThe studies of Robert Hooke 1665 into a plant material would allow the determination of a pore like regular structure surrounded by a wall of which he called cells this in itself unbeknownst to him, was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell. Over 150 years later this can be regarded as one of the most familiar and important facts within the bio...

Protozoa In 1834 Cells
510 words1. Robert Hooke - In 1662, he observed tiny compartments in the cork of a mature tree and gave them the Latin name cellular (meaning small rooms). This was the origin of the biological term cell. 2. Anton Von Leeuwenhoek - By the late 1600 s, he had observed diverse protestant, sperm, even a bacterium - an organism so small it would not be seen again for another two centuries. 3. R. J. H. Dutrochet - French botanist who prepared plant cells and studied them between 1824 and 1830. He discovered a...

Chicken Pox Viral Infection
1,069 wordsChicken Pox Media CHICKEN POX Chicken Pox is a viral infection caused by the varicella-zoster virus, a type of herpes virus. It is contracted by contact with actual lesions or by respiratory secretions and there is a 10 - 21 day incubation period during which your child is developing the illness but does not show any symptoms and is not contagious (until the very last 1 or 2 days before the pox appear. ). Once the vesicles show up there are likely to be many more on the way for between 3 and 7 m...
