Organelles in a Cell
| Term | Definition |
|---|---|
| cytoplasm | semifluid material inside the cell’s plasma membrane |
| cytoskeleton | supporting network of protein fingers that provide a framework for the cell within the cytoplasm |
| ribosome | simple cell organelle that helps manufacture proteins |
| nucleolus | the site of ribosome production within the nucleus of eukaryotic cells |
| endoplasmic reticulum | highly folded membrane system in eukaryotic cells that is the site for protein and lipid synthesis |
| golgi apparatus | flattened stack of tubular membranes that modifies, sorts, and packages proteins into vesicles and transports them to other organelles or out of the cell |
| vacuole | membrane-bound vesicle for temporary shortage of materials such as food, enzymes, and waste |
| lysosome | vesicle that uses enzymes to digest excess or worn-out cellular substances |
| centriole | organelle that plays a role in cell division and is made of microtubules |
| mitochondrion | membrane-bound organelle that converts fuel into energy that is available to the rest of the cell |
| chloroplast | double-membrane organelle that captures light energy and converts it to chemical energy through photosynthesis |
| cell wall | in plants, the rigid barrier that surrounds the outside of the plasma membrane, is made of cellulose, and provides support and protection to the cell |
| cilium | short, hairlike projection that functions in cell movement |
| flagellum | long, tail-like projection with whiplike or propeller motion that helps a cell move |
