How do aquatic plants adapt to the environment? Are fixed to water bed. How Plants Survive In some areas sufficient nutrients or sunlight is not available and sometimesthe plant itself lacks chlorophyll, such plants show certain extreme adaptationsas follows; Insectivorous plants - Insectivorous plants feed on insects due to poor nutrients in the soil.Non-green plants - Since the chlorophyll, which is the green pigment, is absent in the non-greenplants, they depend on dead plants and animals for food. Insectivorous plants have green leaves capable of carrying out photosynthesisto prepare their own food, but they require other nutrients for growth, so theyabsorb these nutrients from the insects they trap. Plants prepare their own food using thenutrients from the soil in the presence of sunlight and chlorophyll. The following figure shows the different type of aquatic plants.

Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater).They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. The plant which lives on land are called terrestrial plants. This has been shown experimentally by bubbling N2 or O2 into the water with rhizomes, and then measuring the ethanol production. The aquatic plants are exposed (especially the totally submerged ones) to the shortage in oxygen which is dissolved in the water, the shortage in the light and the presence of the water currents.. For this reason, plants have developed structural adaptations to minimise the amount of water loss. The presence of specific features or certain habits, which enable a plant or an animal to live in its surroundings, is called adaptation.
