Question

Quizplus · Accepted Answer

Ribosomes are the cellular organelles responsible for protein synthesis, translating mRNA into polypeptide chains. They can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum, making them not exclusively unbound to membranes. They are visible under an electron microscope, which is a common method for studying their structure and function. Ribosomes have no role in photosynthesis, which occurs in chloroplasts in plants and algae.
