It contains air spaces (aerenchyma) within the cells of the petiole
The swollen petiole of the water hyacinth helps the plant float on water by providing buoyancy. It also stores air, which aids in respiration and helps the plant stay afloat. Additionally, the swollen petiole acts as a flotation device to support the plant and allow it to survive in aquatic environments.

Water hyacinth survives by having large inflated sacs in its leaves that help it float on the water surface, allowing it to outcompete other plants for sunlight and nutrients. Its extensive root system also helps anchor it in the water and absorb nutrients. Additionally, its rapid growth rate and ability to reproduce quickly contribute to its survival.
