| Question | Answer |
|---|---|
| Nucleus | Large, surrounded by double membrane Holds all the information and DNA and RNA stuff |
| Nucleolus | Body within nucleus; RNA and protein Site of ribosomal RNA synthesis |
| Chromosomes | Contains genes |
| Cell membrane | Membrane boundary of cell Encloses, protects, regulates movement, holds shape |
| Endoplasmic reticulum | Network of internal membranes Intracellular transport |
| Smooth ER | Lacks ribosomes Lipid biosynthesis, detox |
| Rough ER | Ribosome-studded Protein manufacture |
| Ribosomes | Granules of RNA and protein Synthesize polypeptides |
| Golgi apparatus | Stacks of flattened membrane sacks Modifies, packages, sorts proteins |
| Lysosomes | Membrane sacs Breaks down ingested materials, secretions, wastes |
| Vacuoles | Membrane sacs Stores materials, waste, water, maintains hydrostatic pressure |
| Peroxistomes | Membrane sacs with enzymes Diverse metabolic reactions |
| Mitochondria | Sacs consisting of two membranes;inner is folded Cellular respiration site!! Supplies energy |
| Chloroplasts | Double membrane; encloses thylakoid and chlorophyll |
| Microtubules | Hollow tubes Structural support |
| Microfilaments | Solid, rodlike Structural support |
| Intermediate filaments | Tough protein fibers Strength and stability |
| Centrioles | Pair of hollow cylinders near nucleus Directs things where to go during cell division |
| Cilia | Short hairlike projections Helps move materials on tissue surface |
| Flagella | Long hairlike projections Sperm cell locomotion |
