How Do Some Plants Float in the Water?

Plants that live on top of the water have floats so that they will not sink. They also have roots that act as a weight, so that they will not turn over when the wind blows as they drift along on top of the water. Plants adapt their form to their environments. Water plants, which float and drift along with the currents and winds, have developed very differently from land plants. They have developed floats for buoyancy and root systems that serve as stabilising weights. The water hyacinth can often be seen in goldfish bowls. Water hyacinth and duckweed plants have lots of empty spaces throughout their bodies. These spaces are filled with air. This makes the plants lighter than water and is why they can float in water.
