Question

Water easily trickles off lotus leaves. Why?

• A. Their leaves are thin surfaced.
• B. Their leaves have an oily surface.
• C. Air spaces are present in the leaves.
• D. Leaf surface is covered with dead cells.

Answer 1

The correct option is B Their leaves have an oily surface.

Water droplets easily trickle off lotus leaves because they are covered in an oily surface. This acts as water repellent. The water droplets trickling off also carry the dust particles with them. This helps in keeping the leaves clean.
