organelles & their functions for honors bio
| Question | Answer |
|---|---|
| nucleus | DNA is stored, control center of cell |
| nuclear envelope | separates nuclear material from cytoplasm, regulates materials that go in and out of the nucleus |
| nucleolus | ribosomes are synthesized |
| DNA | genetic material, instructions for reproduction and protein |
| free ribosomes | synthesis of proteins that will be used inside the cell |
| plasma membrane | isolates cell's content, regulates movement of materials in and out of cell |
| cell wall | provides protection, structure |
| smooth endoplasmic reticulum | synthesize lipids used for membrane, detoxify materials |
| ribosomes on rough endoplasmic reticulum | synthesize proteins that leave the cell |
| vesicles | carry materials around cell |
| golgi complex | sorts, modifies, and packages proteins and lipids |
| lysosomes | digests food particles, defective organelles, and excess cell membrane |
| central vacuole | maintains water balance, stores waste, sugars, amino acids, creates turgor pressure |
| food vacuole | temporary food storage |
| mitochondria | extract energy from food, store it, and convert it to ATP |
| chloroplast | capture energy from the sun and convert it to glucose |
| plastids | store various molecules such as starch and pigments |
| cytoskeleton | cell shape, cell movement, organelle movement, cell division |
| cilia & flagella | move cell through fluid or move fluid past cell |
| centriole | provide center for formation of cilia and flagella |
