Question

What is the unusual feature of white water-lilies?

1) They have a unique fragrance
2) They bloom only at night
3) They can change color based on water temperature
4) They have air-filled leaves that help them float

Answer 1

White water-lilies have air-filled leaves that help them float, facilitating sunlight absorption and pollination above water.

Step-by-step explanation:

The unusual feature of white water-lilies is that they have air-filled leaves that help them float. Unlike some plants that may have adaptations like narrow leaves to reduce resistance in moving water, water lilies have broad, flat leaves that float on the water’s surface. This allows them to collect the maximum amount of sunlight, as sunlight does not penetrate deeply below the water’s surface. Their bowl-shaped flowers also stay above water, which is crucial for pollination since pollination by wind or animals isn't feasible underwater.
