Question

Quizplus · Accepted Answer

Veins in leaves are composed of xylem and phloem, ensuring the transport of water, nutrients, and sugars. They are continuous with the vascular bundles in the stem to maintain the flow of substances between the leaf and the rest of the plant. Additionally, they are finely branched to maximize contact with photosynthesizing cells, facilitating efficient exchange of water, nutrients, and sugars necessary for photosynthesis and plant growth.
