| A | B |
|---|
| cell membrane | helps give cell shpe and contrls what comes in and out of cell |
| cell wall | surrounds membrane and gives cell structure |
| centriole | becomes active druing cell division |
| chloroplast | carries out photosynthesis |
| chromoplast | stores pigments in plant leaves like red, orange, and yellow |
| leucoplast | storage plastid in plants |
| chromosome | holds blueprints of cell, controls cellular activity |
| cilia | hairs attached in microtubules |
| cytoplasm | holds everything in cell together |
| cytoskeleton | helps cell move |
| microfilaments | contract to casue movement |
| microtubules | maintain cell shape and serve as tracks for movement |
| endoplastic reticulum | transportation and detoxification |
| flagella | long, whiplike things that are in microtubules |
| gogli bodies | process, packages and secrets organelle of cell |
| lysosome | contains digestive ezymes that breaks down toxins |
| mitochondia | releases energy |
| nucleus | control center of cell |
| nuclear membrane | control what enter and comes out of nucleus |
| nuclear pore | allows large molecules to pass throughhh |
| nucleolus | ribosomes are synthesized and partially assembled |
| ribosomes | produces proteins |
| vacuoles | stores emzymes and waste products |
| concentration gradient | difference in concentration from highest to the lowest number of molecules in a substance |
| hypotonic solution | one in which the concentration of solutes outside a cellis lower then that inside it |
| hypertonic solution | one in which the concentration of solutes outside a cell is greater then that inside it |
| plasmolysis | the cell shrinks |
| cytolysis | the cell explodes |
| isotonic solution | the concentration of solutes is the smae inside and outside the cell |
| homeostasis | self-adjusting balance among life function, the environment, and an organism's activities |
| turgor pressure | pressure that builds in a plant cell as a result of osmosis |
| semi-permeable | allows only certain substances to pass through them |
| osmosis | diffusion of water through membrane |
| diffusion | movement of molecules of substances from aresas of higher concentration of that substance to areas of lower concentration |
| active transport | use of energy to carry molecules across membrane |
| bulk transport | large molecules, food, and other substances are packaged and moved across the membrane |
