Ribosomes

=__**Ribosomes**__ = =Hello, my name is Rob the ribosome. I have a very important job inside of a cell. I make proteins from instructions that come from the nucleus. = =Some people call me a factory worker because I take orders to make proteins from my boss, the nucleus. = =My friends and I hang out throughout the cytoplasm of a cell. Think of cytoplasm as the blood of a cell. = =Ribosomes, like me, are in all sorts of cells, and can vary in quantity depending on how many proteins are needed in that cell. = =We are distinguished by our almost "rough" appearance when we are on things in a cell. There are many of me and we are very small. = = = =I first get my instructions from the nucleus. After i make the proteins, they are sent down to the endoplasmic reticulum, where some of my proteins can be chemically changed to fit the needs of a cell. Finally, the proteins are moved from the endoplasmic reticulum to the Golgi apparatus. Think of the Golgi apparatus as a shipping plant. My proteins are sorted and packaged for storage in a cell or for use outside of a cell. = media type="custom" key="5397247" width="32" height="25" align="left"
