|---|
| cell membrane | controls what gets in or out of the cell |
| proteins | doorways in the cell membrane that lets larger particles in or out of the cell |
| mitosis | the division of cells into two new daughter cells exactly like the mother cell |
| meiosis | cell division that produces four new daughter cells with half the number of chromosomes as the mother cell |
| cytokinesis | the splitting of the cytoplasm during the last phase of mitosis |
| osmosis | the diffusion of water |
| diffusion | the movement of molecules from areas of higher concentration to areas of lower concentration |
| passive transport | cell transport that does not require energy |
| active transport | cell transport that requires energy |
| endocytosis | the taking in of large particles into the cell |
| exocytosis | the release of large particles out of the cell |
| photosynthesis | the process in which plants make their own food |
| respiration | the process in which energy is made from glucose and oxygen |
| glucose | the sugar produced by plants during photosynthesis |
| carbon dioxide | the gas given off during respiration |
| oxygen | by-product of photosynthesis |
| chloroplast | where photosynthesis takes place ina plant cell |
| chlorophyll | captures the sunlight needed for photosynthesis to occur |
| mitochondria | where respiration occurs in all eukaryotic cells |
| water | a product of respiration, besides carbon dioxide and ATP |
| prokaryotes | bacteria cells |
| eukaryotes | plant and animal cells |
| binary fission | cell division of bacteria cells |
| equilibrium | when molecules are evenly spread out |
| consumer | anything that cannot make its own food |
| producer | anything that can make its own food |
| selectively permeable | only lets some things in and keeps other things out; describes the cell membrane |
| products | anything that is listed on the right side of the arrow in a chemical equation |
| reactants | anything listed on the left side of the arrow in a chemical equation |
| 46 | the number of chromosmes in every human cell |
| 23 | the number of chromosmes in egg and sperm cells |
| fermentation | the process of making energy from food when no oxygen is available |
| lactic acid | produced by your muscles when not enough oxygen is avaiable for energy to be made |
| ATP | the energy produced during respiration |
| sunlight | the source of energy necessary for photosynthesis to occur |
