Which of the following describes the xylem?

• The plant stem, leaves, and buds, also contains vegetative and reproductive parts of plants.

• Anchors the plant and absorbs nutrients and water; typically underground.

• Carries sugars (food made by plant) to feed the plant

• capable of absorbing sunlight and transferring that solar/light energy to the chloroplast

How does water travel from the roots to the plan leaf? Name the structure that carries water.

• stomata

• phloem

• chloroplast

• xylem

Which transport tissue allows water to travel upward from the roots to the leaves?

Which statement best explains the importance of the root hairs to the stems and leaves of the plant?

• Root hairs convert minerals into glucose for immediate use by cells.

• Root hairs decrease the need for osmosis and diffusion in vascular tissue.

• Root hairs prevent water loss in leaves through transpiration and gas exchange.

• Root hairs increase the surface area of the roots for nutrient and water absorption.
