ANATOMY

Detailed explanation-1: -The correct answer is (b): ribosomes. A ribosome is an organelle that contains rRNA and ribosomal proteins.

Detailed explanation-2: -Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes (Figure 5).

Detailed explanation-3: -From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.

Detailed explanation-4: -Answer and Explanation: The role of the Golgi apparatus in protein synthesis is that it collects the proteins and ships them off to specific areas. The Golgi apparatus is often known as the post office of the cell.

Detailed explanation-5: -The nucleolus is a condensed region of chromatin where ribosome synthesis occurs. Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis.
