Hydrophytes and Xerophytes

Question 1

What are Hydrophytes?

Answer 1

Plants adapted especially to living in water

Question 2

What are Xerophytes?

Answer 2

Plants adapted especially to living in extreme dry conditions

Question 3

Adaptations of Hydrophytes (Surface) (2)

Answer 3

Thin or non-existent waxy cuticle, many stomata on upper-side of the leaf, almost always open

Question 4

Adaptations of Hydrophytes (Inside) (2)

Answer 4

Large air spaces for buoyancy and gas exchange, fewer xylem (less need for water transport)

Question 5

Adaptations of Hydrophytes (Outside) (1)

Answer 5

Reduced root and stem structure (no need for it)

Question 6

Adaptations of Xerophytes (Surface) (4)

Answer 6

Thick, fleshy surface for defence (multiple layers of epidermi), spikes instead of leaves (so no transpiration), few and sunken stomata

Question 7

Adaptations of Xerophytes (Inside) (2)

Answer 7

Regular sized air spaces, small surface area

Question 8

Adaptations of Xerophytes (Outside) (3)

Answer 8

Trichomes to hold water in sunken stomata, rolled leaves, lateral and beneficial roots
