Which of the following leaf modifications occurs/occur in desert areas to inhibit water loss?
- Hard and waxy leaves
- Tiny leaves or no leaves
- Thorns instead of leaves
Select the correct answer using the codes given below.
Detailed Explanation:
✅ Statement 1 – Correct: Desert plants develop hard, waxy cuticles on leaves to create a waterproof barrier that prevents transpiration and water loss.
✅ Statement 2 – Correct: Reduced leaf size or complete leaf loss minimizes surface area exposed to heat and sunlight, thereby reducing water evaporation.
✅ Statement 3 – Correct: Leaf modification into thorns/spines drastically reduces transpiring surface area while providing protection from herbivores in arid environments.
