AP BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Phloem tissue helps in transfer of food to different parts of plant and Xylem tissue helps in transfer of water and minerals to different parts of the plant.

Detailed explanation-3: -A plant’s roots are found underground and typically grow as deep and wide as the plant grows tall above ground. This provides stability to the plant and stops the plant from falling over. The roots also absorb water, nutrients, and air from the soil.

Detailed explanation-4: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.

Detailed explanation-5: -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.
