Question

describe three ways that a cactus is adapted to prevent water

Answer 1

Answer:

Spines which are modified leaves. These minimise the surface area and so reduce water loss. The spines also protect the cacti from animals that might eat them. Very thick, waxy cuticle to reduce water loss by evaporation .

Cactus are adapted to survive in the hot and humid conditions of the desert. To survive in the desert, cactus has the following adaptations:

(i) Modified flat green stem that prepares food by photosynthesis and conserves water.

(ii) Stem is covered with a thick waxy layer, which helps to retain water.

(iii) Leaves present in the form of spines to prevent water loss through transpiration.

(iv) Long roots that go very deep into soil for absorbing water.
