Cell Organelles
| Term | Definition |
|---|---|
| centrioles | help with cell division |
| lysosome | contains digestive enzymes; the "suicide" sac |
| chloroplast | site of photosynthesis PLANT CELL ONLY |
| golgi apparatus | attach carbohydrates and lipids to proteins from ER; stack of membranes (look like pancakes) |
| endoplasmic reticulum | assemble cell membrane components - "rough" - studded with ribosomes and modify some proteins - "smooth" - no ribosomes; only synthesize lipids |
| vacuoles | storage of food and water Hint: VACUole - VACUum stores dirt |
| mitochondria | "powerhouse" of the cell; site of cellular respiration; makes ATP - primary energy molecule of all cells |
| ribosomes | synthesize (makes) proteins; smallest organelle with important job; makes proteins by assembling amino acids Hint: some ribs have proteins |
| nucleoulus | produces ribosome components |
| nucleus | controls most cell processes and contains hereditary info of DNA; contains nucleolus; surrounded by double membrane called nuclear envelope |
| cytoplastm | clear, watery gelatinous material that contains cell parts |
| cell membrane | a thin membrane that surrounds all cells; separates cell from environment; regulates what enters/leaves cell (selectively permeable - allows passage of certain molecules only); maintains homeostatis |
| cell wall | tough protective layer made of cellulose; protects and supports the cell PLANT CELL ONLY |
