Floating plants give out oxygen during the process of photosynthesis. They also provide shade and shelter for aquatic animals, help in nutrient uptake, and contribute to overall water quality in aquatic environments.
Whales for one
well they will suck water and die.
C4 plants are usually not aquatic, as they are more commonly found in dry, warm environments. C3 plants can include both terrestrial and aquatic plants, as they are more adaptable to different environmental conditions.
The wax on the leaves prevents decomposition of the leaf.
Most aquatic plants require gravel, as they have roots, and will need to grow their roots and attach themselves. There are however lots of floating plant species that do not require gravel, such as duck weed.
Land plants require soil, sunlight, water and different nutrients to grow. Aquatic plants require the minerals and nutrients from in the water to grow.
Floating plants use their unique characteristics, like their ability to attract nutrients magnetically, to thrive in aquatic environments by efficiently absorbing essential nutrients from the water, allowing them to grow and survive in their habitat.
Minute rootless aquatic herbs having globular fronds floating on or near the water surface and bearing one flower per frond. Species of the genus Wolffia are the smallest flowering plants. Commonly called watermeal, these aquatic plants resemble specks of cornmeal floating on the water. Source: Answers.com
aquatic vegetation are plants that grow underwater while vegetation are plants that just grow on land.
Notorious aquatic weeds like water hyacinth get dispersed in vast areas during floods.
Submerged plants can extract nutrients directly from the water column through their roots and not rely solely on their leaves for nutrient uptake, unlike floating plants. Submerged plants also provide shelter and breeding grounds for aquatic organisms in the water column. They can also oxygenate the water more effectively due to their direct contact with the water, contributing to a healthier aquatic ecosystem.
