Science Step 7
| Term | Definition |
|---|---|
| organelles | Tiny cell structures that carry out specific functions within the cell. |
| cell membrane | Controls what materials can travel in and out of the cell. |
| nucleus | The "brain" or "control center" of the cell, which directs all the cells activities. It is amde up of three parts. |
| nucleolus | Where the ribosomes are made. |
| ribsome | Where proteins for the cell are produced. They are made in the nucleolus. |
| mitochondria | Converts food molecules to energy for the rest of the plant to use. |
| choroplast | Capture energy from the sunlight and use it to produce food for the cell |
| lysosome | Small, round structures containing chemicals that break down certain materials in the cell. |
| cell wall | A protective outer covering that lies just outside the cell membrane of plant cells. |
| vesicle | A bound sac in eukrayotic cells that stores or transports the products of metabolism in the cell and is sometimes the site for the breaking down of metabolic waste. |
| smooth endoplasmic reticulum | Makes lipids and breaks down toxins. |
| rough endoplasmic reticulum | Packages and delivers proteins. Has ribosomes on the outside of it. |
| nuclear membrane | It is a double membrane the surrounds the nucleus. |
| cytoskeleton | Gives support to cell, holds cell parts |
| nuclear envelope | Holds nuclear material. |
| DNA | "Instruction manual" for making proteins. |
| golgi apparatus | Packages proteins, receives proteins, and sends them out. |
| centriole | Aids in animal cell devision. |
| unicellular | Consisting of a single cell. |
| multicellular | Composed of many cells. |
| capsule | A membranous sac. |
| animal cell | A form of eukaryotic cell which make up many tissues in animals. |
| plant cell | A cell that is a structural and functional unit of a plant. |
| bacteria cell | A large group of typically unicellular microorganisms. |
| prokaryotic cell | A cell lacking a true membrane-bound nucleus. |
| eukaryotic cell | A cell with a true nucleus. |
| flagellum | Slender cellular appendage. |
| central vacuole | A small cavity in the cytoplasm of a cell, bound by a single membrane and containing water, food, or metabolic waste. |
| cell theory | The theory that cells form the fundamental structural and functional units of all living organisms. |
