organelles
| Question | Answer |
|---|---|
| Nucleus | Stores, protects, manages cell DNA Directs cellular activities → regulates gene expression |
| Ribosome | Creates proteins through translation Docks tRNA to link amino acids together with peptide bonds to form polypeptide chain |
| ER (Smooth) | Synthesizes lipids, phospholipids, & steroid hormone |
| ER (Rough) | Synthesizes, folds, & transports proteins to cell membrane/ other organelles/ outside cell |
| Golgi Body/ Apparatus | Modifies, sorts, packages proteins & lipids Transports proteins & lipids inside/ outside of the cell |
| Lysosomes | Breaks down macromolecules into usable monomers Digest worn out organelles → more space Breaks down viruses |
| Food Vacuole | Stores & digests food Breaks down viruses |
| Contractile Vacuole | Pumps water out of cell to maintain fluid balance |
| Central Vacuole | Holds water & nutrients Expands & drives plant cell growth |
| Mitochondria | Converts nutrients into usable energy (ATP) |
| Chloroplasts | Converts sunlight to chemical energy using photosynthesis |
| Cytoskeleton | Gives cell shape & support |
| Extracellular Matrix (ECM) | Supports structure of cells |
| Cell Wall | Gives cell structural support & shape |
| Flagella/ Cilia | Moving |
| Peroxisome | Breaks down fatty acids & detoxifies substances |
