A cytologist is examining a tissue under an electron microscope.He notices that the endoplasmic reticulum of each cell is extremely rough in appearance and he knows that the rough appearance is because of the ribosomes embedded there.He asks why there are so many ribosomes.You respond,
A)"This tissue exports lipids and is very involved with mRNA production."
B)"This tissue exports proteins to other areas of the body."
C)"This tissue exports various nucleic acids,hence the large number of ribosomes present on the endoplasmic reticulum in each of those cells."

The rough endoplasmic reticulum with ribosomes embedded is responsible for protein synthesis and folding. Therefore, the large number of ribosomes present indicates that the tissue exports proteins to other areas of the body.
