-Floating plants

• Free floating plants float freely on the water surface.
• Trailing floating plants have long and horizontal stems (stolon).
• The stems of trailing floating plants are hollow and can float easily, such as buffalo spinach.
• In free floating plants, the petioles are swollen and spongy consisting of numerous air spaces.
• The presence of these air spaces makes the plants lighter and enables them to float on water.
• An example of a free floating plant is water hyacinth.
• Submerged floating plants are plants that are submerged in water but float on the water surface.
• In submerged floating plants, the petioles are swollen and spongy consisting of numerous air spaces.
• An example of a submerged floating plant is water hyacinth.
