QuestionAnswer
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
