Transport of food substances is mainly carried out in three ways. In plants it is carried out by the vascular tissue called the phloem. In animals it is carried out by the blood circulating in the body. In both plants and animals, food substances are also transported from place to place over longer distances by specialised cells called fat bodies or fat cells. In this post we are going to discuss about some most important Transportation MCQs and Answers. We also published Nutrition MCQs and Answers with FREE PDF that will help you the most.
