The cell
anatomy and physiology: the cell
Term | Definition |
---|---|
what are the 5 characteristics of the cells | reproduce, grow, need for nourishment, elimination of waste, respond |
cell theory | unit of life |
basic cell structure consists of | cell membrane, cytoplasm, the nucleus |
the cell membranes function | the membrane is semi-permeable; impermeable to most water soluble molecules |
proteins | intergral, peripheral; many proteins are enzyme |
Microvilli | fingers that increase the surface area; inside intestine |
membrane junction | tight junction, desmosomes, gap junctions |
what are the two ways of movement through membrane | active processes- require energy passive processes- no energy required |
what are the 7 passive processes | diffusion, simple diffusion, facilitated diffusion, osmosis, osmolarity, tonicity, filtration |
what are the 2 active processes | active transport(ATP), vesicular bulk transport |
5 Types vesicular transport | excoytosis, endocytosis, phagocyosis, pinosytosis, receptor |
Cytoplasm consists of (3) | cytosol, organelles, inclusions |
cytosol | Inclusions, Organelles viscous fluid substance of cytoplasm that is largely water with soluble proteins, salts and sugars |
specific organelles | microchondrdria- powerhouse of the cell |
