AP BIOLOGY

Detailed explanation-1: -Xylem. Xylem vessels transport water and mineral ions from the roots to the rest of the plant. They are made up of dead, hollow cells with no end cell walls. This forms one continuous tube when the xylem cells are stacked on top of each other.

Detailed explanation-2: -Transport in the Xylem The xylem is composed of dead cells with thick, lignified secondary cell walls. These form a low-resistance pathway for the movement of solution. It comprises both narrow tracheids and vessel elements.

Detailed explanation-3: -As transpiration occurs, it deepens the meniscus of water in the leaf, creating negative pressure (also called tension or suction). The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.

Detailed explanation-4: -The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem consists of dead cells. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube.

Detailed explanation-5: -Final Answer: The xylems in plants are responsible for the transport of water.
