Cell Structure

Organelle |Function |Location | |
|Cell (plasma) membrane |Composed of proteins and a bilayer of lipid. |Outermost boundary of cell (animal) |
| |Holds the contents of the cell in place. | |
| |Regulates the movement of materials into and out of the cell using the | |
| |selectively permeable membrane and receptor sites. | |
|Cell wall |Composed of cellulose. |Outermost boundary of plant cell |
| |Protects and support plant cells. Primary and Secondary. | |
| |Pectin, a sticky fluid helps hold the cells together. | |
|Nucleus |Acts as the brain of the cell. It directs all the cell’s activities. |Generally in the center of the cell within the cytoplasm. |
| |Inside the nucleus, hereditary or genetic information is organized into| |
| |threadlike structures called chromosomes. | |
|Nuclear membrane |Holds all the genetic materials within the nucleus. |Outer layer of the nucleus |
|Chromatin |During interphase, the genetic material is called chromatin. |Found within the nucleus.
