The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.

• Phloem

• Stomata

• Chlorophyll

• Xylem

Vascular tissue that transports water and minerals UPWARDS from a plant's roots is know as ______.

• Chlorophyll

• Phloem

• Stomata

• Xylem

How do water enter the roots from the soil?

• diffusion

• osmosis

• transpiration

• active transport

water leaves the plant by ....

• the stomata

• the epidermis

• the palisade cells

• the spongy mesophyll

Transpiration is

• the movement of water through a plant from the roots up the stem

• the loss of water from the leaves of a plant by the process of evaporation

• the flow of water into plant roots by osmosis from the soil

• the process of minerals and sugars moving through plant veins

Why is the evaporation of water from leaves important?

• It cools leaves and helps move water up the plant.

• It makes the plant wilt

• It helps the plant to respire

Where is xylem vessels found in plants

• roots and stems only

• leaves and root only

• roots, stems and leaves

• root hair cells and veins

What do the guard cells do?
