Which best matches the plant tissue to its function?

• Vascular tissue transports materials from the environment into the plant.

• Dermal tissue produces and stores the plant’s food until it is needed.

• Meristem tissue uses energy from the sun to produce food for the plant.

• Ground tissue is the outermost plant tissue that prevents water loss.

How does dermal tissue help plants on a hot day?

• It releases substances so plants can absorb more water from the soil.

• It has a waxy material that prevents the loss of water to the environment.

• parenchyma

• xylem

• phloem
