In most ways, water plants are just like any other kind of plant. They have roots, leaves, stems, and usually flowers. Like all plants, they need sunlight and food in order to grow. They need air to breathe and water to drink.
What makes water plants, or aquatics, different is their ability to grow in a wet, watery environment. Most terrestrial plants cannot tolerate having their roots submerged in wet soil or in water. They are even less tolerant of having their foliage submerged. For water plants, these conditions are beneficial, even vital, to their survival.Their roots, stems, and leaves have adapted so that they require increased water levels in order to survive and grow.They are not hydroponic, which involves growing terrestrial plants in an inert medium, periodically applying a nutrient solution to keep the plants moist.Water plants need water-soaked soil in order to grow and thrive.
