Nucleus |
Location- center of cell Function- keeps DNA & RNA away from potentially damaging reactions in cytoplasm Description- a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane,containing genetic material. |
|
Rough ER |
Location- connected to the ribosomes Function- manufactures membranes & secretory proteins Description- a series of flattened sacs |
|
Smooth ER |
Location- attached to the rough ER cells Function- synthesizes lipids, phospholipids, and steroids. Description- tubule network
|
|
Flagella |
Location- located at the rear end of the microorganism Function- serves as a sensor to the cell Description- a whip-like structure that consists of 3 main parts; an iron motor part, a long filament consisting of the protein flagellin and a hook, basal body with rings |
|
Golgi Body |
Location- located in the cytoplasm next to ER Function- modifies, sorts, ships proteins and lipids for export for insertion into cell membranes Description- these organelles are folded into flattened, membrane-bound sacs, often stacked like pancakes |
|
Plasma Membrane |
Location- vacuoles can be located anywhere in the cell except in the nucleus and in the cell membrane Function- controls the movement of substances in and out of cells Description- the vacuole can get so big that it forces the pliable cell wall to enlarge; cell surface area increases, so the cell can absorb more water and nutrients |
|
Vacuole |
Location- external bound of the cell Function- selectively controls the kinds and amounts of substances moving into and out of the cell; helps maintain cytoplasmic volume, composition |
|
Nucleolus |
Location- in the center of the nucleus Function- a ribosome production factory Description- a round body located in thenucleus
|
|
Cytoskeleton |
Location-in between the nucleus and the plasma membrane Function- structurally supports, imparts shape to cell; moves cell and it's compartment Description- an interconnected system of protein filamets |
|
Cell Wall |
Location- outside of the nucleus Function- protects, structurally supports cell Description- a structural component that encloses the plasma membrane |
|
Chloroplast |
Location-can be found within plasma membranes Function- specializes in photosynthesis Description- 2 outer membranes surround their semifluid interior; the stroma. An inner membrane is folded into flattened disk shapes called thylakoids |
|
Cilia |
Location- lines the surface of some cells Function- moves liquid past the surface of the cell Description- hair-like organelles |
|
Mitochondria |
Location- found in cytoplasm Function- energy powerhouse; produces many ATP by aerobic respiration Description- the organelle contains 2 membranes, and the innermost one is extensively folded and together they form two compartments inside the mitochondrian. |
|
Lysosome |
Location- scattered in cytoplasm Function- digests ingested materials Description- tiny sacs filled with fluid containing enzymes |
|
Ribosome |
Location- attached to the membrane systems or scattered in the cytoplasm Function- synthesize proteins Description- a tiny, somewhat mitten-shaped organelle |
|
Cytoplasm |
Location- fills the cell Function- moves materials around the cell & dissolves cellular waste Description- gel-like appearence |
