Correct Answer: A
Solution :
[a] RER (rough endoplasmic reticulum) bears ribosomes on their surface. RER is involved in protein synthesis and secretion. Cell wall is a characteristic feature of plant cell, bacteria, fungi, algae and some archaea. The major function of the cell wall is to provide rigidity, tensile strength, structural support, protection against mechanical stress and infection. Flagella are a slender thread- like structure, especially a microscopic whip-like appendage which enables many protozoa, bacteria, spermatozoa, etc. to swim. It is responsible for cell movement. Lysosome is a single membrane bound vesicular structure and contains many hydrolytic enzymes. It is commonly called as suicidal bag of the cells and involved in intracellular and extracellular digestion.
