Just Organelles
Organelles and their function
| Question | Answer |
|---|---|
| Chromatin | is a mass of genetic material composed of DNA and proteins that condense to form chromosomes |
| Cell | the basic biological unit of living organisms containing a nucleus and a variety of organelles enclosed by a limiting membrane. |
| Cilia | tiny hair-like projections on cell surfaces that move in a wavelike manner |
| Lysosomes | organelles that originate from the Golgi apparatus and contain strong digestive enzymes |
| Microvilli | the tiny projections on the free surfaces of some epithelial cells, increase surface area for absorption |
| Mitochondria | the rod like cytoplasmic organelles responsible for ATP generation for cellular activities |
| Nucleolus | sperical body within the nucleus, composed of protein, DNA, and RNA, that functions in the synthesis and storage of ribosomal RNA |
| Nucleus | a dense central body in most cells containing the genetic material |
| Organelles | specialized structure in a cell that perform specific metabolic functions |
| Peroxisomes | organelle similar to lysosomes that contains enzymes that use molecular oxygen to oxidize various organic compounds |
| Plasma membrane | membrane that encloses cell contents, regulates what enters and leaves the cell |
| Ribosomes | an organelle in the cytoplasm of cells that synthesizes proteins |
| Endoplasmic Reticulum (ER) | a network of channels running through the cytoplasm of a cell that serves in intracellular transportation, storage, synthesis, and packing of molecules |
| Smooth ER | type of endoplasmic reticulum involved with the production of lipids (fats), building blocks for carbohydrate metabolism, and the detoxification of drugs and poisons |
| Rough ER | type of endoplasmic reticulum, covered in ribosomes, involved mainly with the production and processing of proteins that will be exported, or secreted, from the cell. |
