Question

Water hyacinth is an aquatic plant that floats on water. Explain its modifications in brief.

Answer 1

Water hyacinth is a free-floating perennial aquatic plant.

Modifications:

• The roots and root hairs are poorly developed since water availability is not a problem unlike terrestrial plants.

• The stem is flexible and it can sway along with water currents.

• The leaves have a water resistant waxy coating that prevents them from decaying in water.
