• roots 
• leaves 
• all of the above

The plant transport system are made up of ____ types of tubes.

• 1
• 2
• 3
• many

What is the name of the part of the root that allows water and minerals enter?

• root hairs
• epidermis
• phloem
• phyla

what is the function of root hair?

• it is place to store the food
• it has large surface area to absorb more water

How do water enter the roots from the soil?

• diffusion
• osmosis
• transpiration
• active transport

Water vapour exits a plant leaf 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

Which of these is true?

• Xylem vessels carry water and dissolved minerals up the plant
• Phloem tissue carry water and dissolved minerals up the plant
• Xylem vessels carry dissolved sucrose up and down the plant

What happens to the transpiration rate as light intensity increases?

• It increases
• It stays the same
• It decreases
