Science Unit 3 Flash Cards - Cell
Term | Definition |
---|---|
Ribosomes | Building site for the proteins of the cell |
Cell Membrane | Thin membrane that surrounds the cytoplasm of a cell; regulates the passage of materials in and out of the cell. |
Rough ER | Clear tubular passageways studded with ribsomes; for transportation of materials through the cell |
Vacuole | Stores water and food in both plant and animal cells (larger in plants) |
Structures | How the parts are put together |
Centrioles | Tube-like structures that exists in pairs in animal cells; guides the chromosomes during cell division |
Nucleus | Found in eukaryotic cells; contains genetic material (DNA) responsible for controlling the activities of the cell |
Mitochondria | Functions in energy production; the powerhouse of the cell |
Lysosomes | Holds waste materials from the cell; breaks down food, worn out pieces of cells and other waste. Generally found in animal cells |
Flagellum | Long whip-like structure that allows a cell to move |
Smooth ER | Clear tubular passageways (free of ribosomes); for transportation of materials throughout the cell |
Golgi Body | Stores, packages, and ships cellular materials |
Cell Wall | Surrounds the cell membrane of a plant cell to give structure and protection to the cell |
Cell Theory | Cells are the basic unit of all living things, all living things are composed of one or more cells, all cells come from pre-exisiting cells |
Chloroplast | Green organelle in plant cells that converts light energy into chemical energy |
Chromosomes | Found in the nucleus and made of DNA, these contain genetic information of the cell |
Cilia | Hair-like structures that extend from the surface of the cell to help with movement |
Cytoplasm | Jelly-like material that fills the cell; and in eukaryotic cells, surrounds the nucleus |
