Which of the following is most likely to be found in a desert environment?

a. broad leaves to capture sunlight

b. spines instead of leaves

c. needle-like leaves

d. wide, flat leaves that can float

The desert climates are mainly arid. It is a climate in which the rate of evaporation is much more than precipitation. The rocky and sandy surface holds little moisture and evaporates maximum moisture whenever they receive rainfall.

Some animals and plants are adapted to the desert climate. Plant parts are modified to prevent excess water loss. In hot climates, plants such as cactus have leaves that are modified to spines along with their stem also have spines. This typical modification helps to conserve water and prevents excessive water loss. Various remarkable adaptations have evolved that enable plant species to survive in harsh and stressful habitats.

Broad leaves can cause excess water loss in desert climates.

Needle-like leaves are found in coniferous forests or colder climates.

Wide, and flat leaves are found in aquatic plants that can float.

Therefore, ‘b’ is the correct option

In desert climates, most of the leaves are modified to spine and thrones that ensure lesser transpiration pull and prevent excessive water loss.
