cells structure
Question | Answer |
---|---|
Plasma Membrane | Encloses the cell contents, main function is to control what gets into and out of the cell. |
Microvilli | Short extensions of cell membrane the absorb materials into the cell |
Nucleus | Largest organelle in the cell it contains the genetic material for the cell |
Nucleolus | Found within the nucleus. It's job is to assemble ribosomes |
Cytoplasm | Contains primarily water and protein material. "Soup of the cell" |
Cytosol | Fluid portion of the cytoplasm the surrounds organelles composed of nutrients, minerals, enzymes, and other specialized materials in water |
Smooth ER | A series of interconnecting flattened tubular tunnels that DO NOT have ribosomes . Is the place for lipid synthesis |
Rough ER | A series of interconnecting flattened tubular tunnels that DO have ribosomes. Takes ribosomes so they do not escape into the cytoplasm. |
Ribosomes | Where protein synthesis takes place. Attached to the rough ER |
Mitochondria | Produces ATP, power house of the cell |
Golgi Apparatus | Composed of small membranous sacs. Packages proteins from the ER before being moved to their final destination |
Lysosomes | membrane-bound sacs of digestive enzymes. They breakdown old or unneeded parts of the cell into small organic molecules that can be reused |
Peroxisomes | membrane-enclosed organelles containing enzymes that break down harmful substances |
Vesicles | small membrane-bound sacs in the cytoplasm that store materials and move materials into or out of the cell in bulk |
Centrioles | Rod shaped bodies (usually 2) near the nucleus that help separate the chromosomes during cell division |
Surface projections | Extend from the cell and move the cell of fluids around the cell |
Cilia | Short, hairlike projections from the cell that move the fluids around the cell |
Flagellum | Long, whip like extension for the cell that moves the cell |
Plasma Membrane | Encloses cell contents, Participates in cellular activities, Bi-layer structure |
