Cells
| Term | Definition |
|---|---|
| Nucleus | Contains DNA and is the control center of the cell. Its one of the largest organelles. Materials pass into and out of it through pores in the nuclear envolpe |
| Chloroplast | In plant cells the sites where photosynthesis take place in a plant cell. |
| Mitochondria | Converts energy stored in food to energy the can use to live and function |
| Ribosomes | Functions as factories that make proteins for the cell can attach to ER can float around in cytoplasm |
| Endoplasmic Reticulum | Structures that look like a maze. A network of folded membranes that move materials throughout the cell |
| Golgi Body | When proteins leave ER they go to the Golgi body is the site where proteins are packaged and distributed |
| Lysosomes | Organelles that contain chemicals which digest waste products and worn out cell parts. Releases material that can be used again |
| Vacuole | Storage part of a cell. Acts as temporary storage center- stores water, food, and other materials needed by a cell |
| Cell | are the smallest/basic unit of life that conducts all life functions. Cells vary in size and shape but contain most of the same parts Bacteria are the smallest organisms made of 1 cell |
| Cell Discovery | The first cells from an organism were observed by Robert Hooke in the 1600s. Soon after microscopist van Leeuwenhoek observed many other living cells. |
| Cell Theory | All living things are composed of 1 or more cells, the cell is the basic unit of structure & function in living things, new cells are produced |
| organelle | tiny cell structures that carries out specif functions within the cell |
| Cell Wall | Ridgid layer surrounding plant cells and some other organisms (but not animal cells) |
| Cell Membrane | The thin, flexible barrier surrounding the cell. |
| Cytoplasm | the clear gel like fluid inside of a cell made out of mostly water and some salt. |
| Photosynthesis | occurs in chloroplast, plants use sunlight , carbon dioxide and water to make simpler sugars, plant cells release oxygen once the sugars are formed, they are either used by the plant or stored in vacuoles. |
| Respiration | occurs in the mitocondria of the cells the cell uses energy to build, repaired, & reproduce cells |
| Waste Elimination | organisms get rid of waste that can be harmful to the cell this occurs in lysosomes |
| Mitosis | is cell reproduction that occurs in nucleus of the cell it enables to make an exact copy of itself |
