Cells
| Term | Definition |
|---|---|
| Organelles | A tiny cell structure that carries out a specitficfunction within a living cell |
| Cell Wall | A ridged supporting layer that surrounds the cells of a plant and some other organisms |
| Cell Membrane | A thin flexible bairreir that surrounds a cell and controls what goes into the cell and out of a cell |
| Cytoplasm | The thick fluid region of a cell located inside of the cell membrane or between the cell and the nucleus |
| Nucleus | In cells a large oval organells that contains the cells genetic material in a form of DNA |
| Mitochondiran | Rod shaped organells that convert food into energy for the cel so it can function |
| Chlrooplast | An organelle in the cells of a plant in some other organisms that capture sunlight to turn it into food |
| Valcule | A sac like organelle that stores water, food, and other materials |
| Selectively Permeable | A property of cell mebranes that allows some substiances to pass across it, while others cannot |
| Diffusion | The process by which molocules move form an area of higher concentration to an area of low concentration |
| Osmosis | Th diffusion of water molocuels across a selectivly permiable membrane |
| Exocytosis | The process by which the volocule surroudig particles fusses with a cell membrane, forcing contents out of a cell |
| Endocytosis | The process by whch a cell membrane takes particals into the cell by changing the shape and engoulping particals. |
| Cell Cycle | The siers of events in which a cell grows and prepares for division. |
| Interphase | The first stage of the cell cycle that takes place before cell dividsion occurs. |
| Replication | The process in which a cell makes a copy of the DNA before cell division. |
| Mitosis | The second stage of a cell cycle durring which the cells nuclues divides into two new nuclie and one set of DNA is distubuted into each daughter cells. |
| Cytokinesis | The final stage of the cell cycle, in which the cells cytoplasm divides distrbuting the two new daugter cells. |
| Photoythinsis | The process by which plants make thier own food and othe autotrophs capture and use their own light energy to make food from carbon dioxide and water. |
| Autotroph | An organism that is able to capture the energy form sunlight and use it to produce its own food |
| Heterotroph | An organism that cannot make its own food and gets its food by consuming other things |
| Chlorophyll | A green phootosynthysis pigment found in chloroplast in plants, algea, and some bacteria. |
| Cellular resperation | The procces in which oxygen and gluclose undergo a complex sieris of chimechal eactions inside cells |
| Frmentation | The realese of energy from foodwithout using oxygen |
| Produce | Makeing |
| Source | The products of cellular resperation are carbon dioxyide and water |
