Question | Answer |
---|---|
Basic living structure | CELL |
3 PARTS OF THE CELL | 1.Plasma Membrane 2.Cytoplasm 3.Nucleus |
Intracellular Fluid | Cytoplasm |
Extracellular fluid | any fluid outside of cell |
Fluid mosaic model | Phospholipid bilayer |
"sugar coating" used for cells to ID other cells | glycocalyx |
Proteins mounted in the PM | Integral proteins |
Proteins loosely mounted to integral proteins | Peripheral proteins |
Junction that forms an impermeable junction. | Tight junction |
Communicating junction between cells | Gap junction |
Fluid between cells | Interstitial fluid or intercellular fluid |
Diffusion along a concentration gradient | Simple diffusion |
Diffusion aided by protein carriers or channels | Facilitated diffusion |
Diffusion of water | Osmosis |
Soln with the same tonicity as the cell | Isotonic |
Soln with higher tonicity than the cell | Hypertonic |
Cells immersed in hypertonic soln will: | Shrink (crenate) |
Soln with lower tonicity that the cell | Hypotonic |
Cells immersed in hypotonic soln will: | Swell and burst (lyse) |
Movement against a concentration gradient | Active transport |
Transport requiring energy | Active transport |
Sodium potassium pump is an example of: | primary active transport |
Vesicles move substances out of the cell in: | exocytosis |
Cell ingests a substance in the process of: | endocytosis |
Vesicles move a substance across a cell in: | transcytosis |
A cell engulfing solid material | Phagocytosis |
A cell engulfing fluid | Pinocytosis |
Cellular material between the PM and nucleus | Cytoplasm |
Components of cytoplasm | cytosol, organelles, inclusions |
powerhouse of the cell | mitochondria |
traffic director and packaging center | golgi apparatus |
disintegrator bodies | lysosomes |
small motile extensions of the cell | cilia |
long motile extensions of the cell | flagella |
tiny extensions of the PM | microvilli |
Cell control center | Nucleus |
