animals/plants in water conditions

• hydrophytes are adapted to live in water.
• root hairs are absent because leaves and stems absorb water.
• conducting tissues such as xylem are absent because they is no need for water to go around the plant.
• absence of cuticles on the leaves enables the leaves to absorb water from surrounding areas where plants live.
• aquatic animals have various ways that they adapt to live in water, for example, fish and crabs have gills, so that they can breathe in water
• many aquatic animals have scales or slime coating their skin, these protect against predators and parasites and helps them swim quicker
• some aquatic animals have fins, which allow them to swim faster and easier
• fish have streamlined bodies which helps them move through the water more easily.
• fins also allow fish to change direction quickly when swimming.
• the shape of an animal's body is important as it affects how well it moves through its environment.
