Question

Give an account of the ecological adapatation in hydrophytes.

Answer 1

• In biology, an adaptation is a form of change that is maintained by the natural selection process.
• Adaptations allow an organism to be better suited to its present conditions and more likely to reproduce or reproduce more successfully.
• Hydrophytes are plants that have adapted to life in very wet places, So much so that they only live on or in water itself.
• You can remember hydrophytes for the 'hydro-' part of their name, meaning 'water.'
• Hydrophytes like the water lily have little to no root system, unlike land plants, because roots simply aren't as necessary since water is so readily available.
• Most leaves in hydrophytes are thin, and many can float freely.
• The part of plants that allow for gas exchange, called the stomata, are located only on the part of the plant surface that's exposed to air.
• Finally, underwater plants will often lack stomata since they no longer need to exchange gases with the atmosphere anymore. They instead exchange gases with the water they live in.
