Worked Solution & Example Answer:Which leaf structures are adaptations to assist in the conservation of water? (A) Central vein, irregular leaf shape (B) Large air spaces, pointed leaf tip (C) Spongy mesophyll, vascular bundle (D) Sunken stomates, thick waxy cuticle - HSC - SSCE Biology - Question 7 - 2007 - Paper 1
Step 1
Identify the suitable adaptation
Answer
The correct answer is (D) Sunken stomates, thick waxy cuticle.
Explanation: Sunken stomates are located below the leaf surface and help to reduce water loss by creating a humid microenvironment. The thick waxy cuticle on the leaf surface also minimizes evaporation of water. Together, these adaptations effectively assist in the conservation of water in plants.
