AP BIOLOGY

Detailed explanation-1: -Water is transported from the petiole through the lamina mesophyll by the vein xylem, while sugars are transported from the leaf to the rest of the plant via the phloem.

Detailed explanation-2: -Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells. They move water.

Detailed explanation-3: -Phloem are tissues that look like tubes. They transport sugars throughout the plant and supply it to tissues like roots, flowers and fruits that depend on this sugar to grow. Think of them like the veins in our body that move blood.

Detailed explanation-4: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Detailed explanation-5: -Phloem is tissue that delivers food, made in a plant’s leaves during photosynthesis, to the rest of the plant.
