The stem part becomes buoyant and due to this, the water hyacinth floats on the surface of the water.

Detailed explanation-2: -A special type of parenchyma tissue called aerenchyma helps plants to float in water. It is present in aquatic and some land plants. Aerenchyma forms a spongy tissue that consists of air providing buoyancy to the floating plants.

Detailed explanation-3: -Such, parenchyma cells are called as aerenchyma. Water hyacinth possess such cells, which make them enable to float in water. Was this answer helpful? 0.

Detailed explanation-4: -A special type of parenchyma; called aerenchyma is present in water hyacinth. This tissue has air-filled spaces inside and because the air gets trapped in the stem part it becomes buoyant. Due to this, water hyacinth floats on the water surface.

Detailed explanation-5: -In aquatic plants, large air cavities are present in parenchyma to give buoyancy to the plants to help them float.
