Xerophytic Plants

Question 1

What are xerophytic plants?

Answer 1

Plants which live in hot conditions

Question 2

What are the adaptations of xerophytic plants?

Answer 2

Rolled leaves
Sunken stomata
Thick waxy cuticle
Low stomata density
Small leaf surface area

Question 3

Explain how rolled leaves are efficient for xerophytic plants in preventing water loss

Answer 3

• less steep water potential gradient

Question 4

Explain how sunken stomata, stomatal hairs (trichores) are efficient for xerophytic plants in preventing water loss

Answer 4

Less steep water potential gradient

Question 5

Explain how having a thick waxy cuticle is efficient for xerophytic plants in preventing water loss

Answer 5

Prevents water loss
Diffusion distance increases

Question 6

Explain how having a small leaf surface area is efficient for xerophytic plants in preventing water loss

Answer 6

Decreases the rate of diffusion

Question 7

Explain how having a low stomata density is efficient for xerophytic plants in preventing water loss

Answer 7

Decreased rate of diffusion
