Free ribosomes freely float in the cytoplasm of the cell and the membrane-bound ribosomes bind to the nuclear membrane or to the endoplasmic reticulum. Ribosome function is vital for the production of proteins, or polypeptide chains, from the mRNA.
Ribosomes are found in ALL cells: plants, animals, bacteria, yeast,etc. They are the sites for protein synthesis. All living things need to have them. both! they create protien for both plant and animal cells. the way i remember it that RIBS give you protien(since they are meat) RIBosomes.
