IGCSE Plant Transport

What is the function of xylem tissue?

• Transport nutrients from the leaves to the rest of the plant

• Transport water, mineral ions, and solutes from the roots to the leaves

• Absorb water, mineral ions, and other nutrients from the soil

• Absorb nutrients from the leaves

What is the function of phloem tissue?

• Transport nutrients from the leaves to the rest of the plant

• Transport water, mineral ions, and solutes from the roots to the leaves

• Absorb water, mineral ions, and other nutrients from the soil

• Absorb nutrients from the leaves

Where can you find xylem and phloem in a plant?

• Leaf, stem, and root

• Leaf and stem

• Stem and root

• Leaf and root

How does water enter the root?

• Through the stomata

• Through the xylem vessels

• Through the root hair cells

• Through the phloem tissue

What is the pathway of water through a plant?

• Root hair, cortex, endodermis, xylem

• Xylem, endodermis, root cortex, root hair

What factors affect the rate of transpiration?

• Temperature and humidity

• Temperature and pressure

• Humidity and pressure

• Humidity and concentration gradient

What is transpiration?

• The movement of sucrose and amino acids in the phloem

• The loss of water vapour from leaves via the stomata

• The movement of water from the roots to the leaves

• The absorption of water, mineral ions, and nutrients from the soil
