CELL

Golgi body is the part in the cell that prepares and store chemical products, its like small sac of membrane are pinch away from the cell. It packaged the proteins in vesicles and sent them out of the cell membrane, of course proteins isn’t the only one that is send away. The size and the number of the Golgi bodies in a cell depends on the quantity of chemicals product in the cell, the more it produce the more and bodies are found.

 

Ribosome is where the cell assembles proteins according to the genetic instructions, in human cells there’s a few million in it. Most of the proteins are made by free ribosome, proteins that are made by the bound ribosome usually export from the cell. The ribosome is made up of two subunits, each of them has its own mix of ribosomal RNA and proteins. These subunits join together to form a functional ribosome only when they attach to a messenger RNA molecule. Ribosome functions in protein synthesis. As they move along messenger RNA, amino acids are joined in an order originally dictated by DNA. Several ribosomes can be moving along the same messenger RNA at once.
