Which of the following leaf modifications occurs/occur in desert areas to inhibit water loss?<br/>1. Hard and waxy leaves<br/>2. Tiny leaves or no leaves<br/>3. Thorns instead of leaves<br/><br/>Select the correct answer using the codes given below.

1. Hard and waxy leaves — Correct. Xerophytes often have thick, leathery leaves with a waxy cuticle to reduce transpiration.
2. Tiny leaves or no leaves — Correct. Reduced leaf area, or complete absence of leaves, minimizes water loss in desert plants.
3. Thorns instead of leaves — Correct. In many desert plants, leaves are modified into spines/thorns, which greatly reduce transpiration.

Hence, all three are adaptations to inhibit water loss in desert areas.
