A) A bioluminescent bacterial cell
B) A functional phloem at maturity
C) An amoeba engulfing small ciliates
D) A pancreatic cell engaged in the production of digestive enzymes
Correct Answer: D
Solution :
Endoplasmic reticulum helps in the transport of substances within the cell. Rough endoplasmic reticulum (RER) bears ribosomes on the cytoplasmic surface and synthesises secretory and membranous proteins. Then the modified proteins move into the transitional area where they are further processed and packed into secretory vesicles. Thus, RER is rich in cells which are actively engaged in protein synthesis and secretory activity, e.g., pancreatic cells engaged in the production of digestive enzymes, etc.You need to login to perform this action.
