An Analysis of Cell Components - Essay Example

In many ways, plant cells are similar to other eukaryotic cells. They have (usually just) one nucleus, organelles, and a plasma membrane, and (almost all of them) share connections to adjacent cells. Cell walls and chloroplasts are the major plant cell distinctive features (Bowes, 1996). Protein synthesis occurs at tiny organelles called ribosomes. Ribosomes are composed of a large subunit and a small subunit. Ribosomes can be found alone in the cytoplasm, in groups called polyribosomes, or attached to the endoplasmic reticulum (Bowes, 1996).

The cytoplasm is a jelly-like substance. It contains the nucleus and other cell structures (organelles). The cytoplasm contains enzymes, and most of the chemical reactions take place there. Cytoplasm operates as a "molecular soup" that binds together all of the cell's organelles and separates the organelles within the cell. Cytoplasm is believed to be the origin of the cytoskeleton. The cytoskeleton supports the movement of the cell as well as its anatomy through cytoplasmic streaming.

This occurs when the cytoskeleton moves to press the cell membrane it is then when the cytoplasm moves and occupies the space (Francis, 1996).
