Plasmodesma |
Communication junction between adjoining cells. |
|
|
Mitochondrion |
Energy powerhouse; produces many ATP by aerobic respiration. |
|
|
Cytoskeleton |
Structurally supports, imparts shape to cell; moves cell and its components. |
|
|
Microtubules |
Cytoskeletal elements involved in cellular movement; hollow filament of tubulin subunits. |
|
|
Microfilaments |
Reinforcing cytoskeletal element; a finer of actin subunits. |
|

Stable cytoskeletal element that structurally supports cells and tissue. |
|
|
Cell Wall |
Protects, structurally supports cell. |
|
|
Chloroplast |
Specializes in photosynthesis |
|
|
Central Vacuole |
Increases cell surface area; stores metabolic wastes. |
|
|
Nucleus |
Keeps DNA separated from cytoplasm; makes ribosome subunits; controls access to DNA.
|
|
|
Nuclear Envelope |
A double membrane that constitutes the outer boundary of the nucleus. Pores in the membrane control which substances can cross. |
|

|
Nucleoplasm |
Viscous fluid enclosed by the nuclear envelope. |
|
|
Ribosomes |
Assembling polypeptide chains. Sites of protein synthesis. |
|
|
Rough ER |
Modifies proteins made by ribosomes attached to it. |
|
|
Soft ER |
Makes, lipid, breaks down carbs and fats, inactivates toxins. |
|
|
Golgi Body |
Finishes, sorts, ships lipids, enzymes, and proteins.
|
|
|
Lysosome |
Digests, recycles materials. |
|
|
Vesicles |
Transporting, storing, or digesting substances in a cell. |
|
|
Plasma Membrane |
Selectively controls the kinds and amounts of substances moving into and out of cell; helps maintain cytoplasmic volume, composition. |
