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 |
