To suggest: A possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf from the given statements (a) and (b). Introduction: Vascular plants consist of two specialized tissues called xylem and phloem that act as a conducting tube in plants for the transportation of water and sugar molecules throughout the plant. The xylem vessel helps in transporting the water and minerals from the roots to the leaves, and the phloem vessels are involved in transporting the prepared food (glucose) from leaves to all parts of the plants.

Question

Features Features The presence of a single cotyledon in the seedling is the most common way to identify monocot plants. Veins that run parallel to the length of the leaves and flower sections that are arranged in a three or six-fold symmetry are some of the anatomical characteristics shared by monocots. Monocots have very little true woody tissue and an adventitious root system. They lack a typical cambium and have scattered vascular bundles.

The vascular system in piants is made up of two tissues: phloem and xylem. (a) Mark on the image above the positions of the xylem and phloem. (b) Differentiate between these vascular tissues. (c) Identify and describe a recent technology used to determine plant structure.

Given that (a) xylem is located toward the upper epidermis in leaf veins and phloem is located toward the lower epidermis and (b) the vascular tissue of a leaf is continuous with that of the stem, suggest one possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf.
