Question

1. Thorn forests have plants that have small leaves.
2. This helps to minimize water loss due to transpiration.

Options

• (B) contradicts (A).

• (B) is the reason for (A).

• (A) is true but (B) is false.

• (A) and (B) are independent of each other.

Answer 1

(B) is the reason for (A).

Explanation:

Thorn forests are made up of plants with extremely small leaves or leaves that have been converted into thorns as an evolutionary adaptation to withstand severe droughts. Reducing the surface area of the leaf reduces water loss through transpiration, allowing plants to store their scarce moisture in arid environments.
