organelles
| Term | Definition |
|---|---|
| nucleus | holds dna |
| prokaryotic | no nucleus |
| eukaryotic | nucleus |
| cell theory | everything is made of one or more cells cell is the basic unit of structure and function all cells arise from pre existing cells |
| cell membrane | acts as a protective barrier to the uncontrolled flow of water |
| mitochondria | Provides the cell with energy |
| vacuole | Helps with the release of cellular waste |
| lysosome | Contain hydrolytic enzymes necessary for intracellular digestion |
| ribosome | - contains RNA and the site of protein synthesis |
| Cytosol/cytoplasm | The cytosol is the "soup" within which all the other cell organelles reside and where most of the cellular metabolism occurs. This is a collective term for the cytosol plus the organelles suspended within the cytosol. |
| rough er | Proteins synthesized on these ribosomes collect in the endoplasmic reticulum for transport throughout the cell |
| smooth er | Smooth ER plays different functions depending on the specific cell type including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and control of calcium release in muscle cell contraction. |
| Golgi | It is actually a stack of membrane-bound vesicles that are important in packaging macromolecules for transport elsewhere in the cell |
| dna | genetic material |
| cytoskeleton | the internal framework of cell |
| flagella | used for movement |
