Term | Definition |
---|---|
cell membrane | allows molecules to pass in (enter) and out of (leave) the cell |
cell wall | PLANTS ONLY, rigid structure that protects cell from injury and provides support |
chloroplast | PLANTS ONLY, site of photosynthesis which converts energy from the sun into glucose (sugar) |
cytoplasm | gel-like fluid between the nucleus and cell membrane that holds the organelles |
endoplasmic reticulum | can be rough or smooth, moves materials to other parts of a cell |
golgi apparatus (body, complex) | processes, packages & transports proteins |
lysosome | contains digestive enzymes that break down discarded proteins (food, worn out organelles) |
mitochondria | site of cellular respiration which generates energy (ATP) for cells |
nucleus | "control center," directs activities of the cell, stores and protects DNA, location where DNA is copied to RNA |
organelles | internal cell parts that perform specific functions in the cell, "little organs" |
ribosome | site of protein synthesis |
vacuole | PLANTS ONLY, storage sacs for nutrients (food), waste & water |
