Question

4. Discuss about plants that adapt themselves to survive in an aquatic habitat.​

Answer 1

• These plants require special adaptations for living submerged in water, or at the waters surface. The most common adaptation is aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is permanently saturated with water.

Answer 2

Answer:

• In aquatic plants, roots are much reduced in size and their main function is to hold the plant in its place.
• The stems may be reduced or long, slender, flexible and spongy. The air spaces in spongy stems make them buoyant.
• Thin and large flat leaves with waxy surface. This protects leaves from wetting and decaying.
• The leaves of submerged plants are thin and narrow. Such leaves allow the water to flow without damaging them.
