Plant Cell There are two classes of cells that exist in biology today, there are prokaryotic cells and there are eukaryotic cells. A prokaryotic cell is a cell that has no nucleus which consists of bacteria; a eukaryotic cell is a cell that has a nucleus. There are two types of eukaryotic cells in biology; plant and animal cells. Plant cells have organelles in each cell that helps then function and go through processes such as photosynthesis. Each cell in our body consists of organelles that help the cell function. All plant cells have a nucleus which consists of a nucleolus, nuclear envelope and nuclear pores. The nucleus is an oval shape which contains the nucleolus and DNA. The process of DNA being altered into RNA takes place within the nucleus; the nucleolus is the site of RNA synthesis and also contains RNA and Protein. The Nuclear envelope consists of two membranes its function is to separate the content within the nucleus from outside of the cell. The nuclear pores control the passage of proteins between the cell’s cytoplasm and plasma of the nucleus. Plants contain certain organelles that animal cells do not contain which is a cell wall which is the cell wall; it functions as the structural support for the plant cell. Other organelles within the animal cell consists of a plasma membrane which is a structure that surrounds all cells, the plasma membrane separates the organelles with in the cell from the Interstitial fluid the plasma membrane also acts as a selective barrier that allows exchanges in and out of the cell. Then there is the Golgi apparatus that consists of flattened membrane stacks which…
