There are three common categories of aquatic vegetation: emergent, submergent and floating.
Let's look at the three main categories of aquatic plants: submerged, emergent, and free floating.
For example: lotus, vallisneria, water chesnut, hydrilla, water hyacnith etc.
The plants can be categorized into four main types. Submerged plants, emergent plants, floating plants, and algae.
What characteristics are common to all plants? They are multicellular eukaryotes. They have a specialized reproductive organ. They produce food through photosynthesis.
Algae. Algae are the oldest and most common type of aquatic plant. They are found primarily in the ocean and they have no roots, stems or leaves. Algae are extremely small but they are the basis of the ocean food chain.
Submerged plants
The leaves, stems, and roots grow entirely underwater although some of its leaves float. In addition, they have flowers usually raised above the water surface. They usually grow near the shore up to the deepest part of the littoral zone.
Aquatic plants are supported by their buoyancy in water and do not need a rigid stem; flotation devices such as gas-filled stomata and intercellular spaces hold them upright and enable them to grow toward the water surface and obtain sufficient sunlight for photosynthesis.
Plants have evolved considerably since first appearing in the oceans approximately 540 million years ago. Cambrian Period 539 to 485 million years ago: Green algae is present in oceans. Ordovician Period 485 to 443 million years ago: Bryophytes appear (liverworts, hornworts, and mosses) with spores.
All animals that live in freshwater bodies like rivers, ponds, lakes, etc., are adapted to live only in freshwater. Examples: Freshwater fishes, mosquitoes, Hippopotamus, river otter, etc., Plants like Lotus, water hyacinth, duckweed live in freshwater.
Anubias is another excellent choice for option one. Like Java Fern, they will grow submerged, emergent or completely out of the water. Growing out of the water, Anubias, unlike Java Fern, will send some roots down into the substrate. The number of roots can vary from a single root to a jungle-like mass.
Aquatic plants include the marine plants that grow in seawater and the freshwater plants that grow in freshwater habitat like ponds, lakes and rivers. Water lily and lotus are examples of aquatic plants.
Generally, any plant that flops over lazily when removed from the water is a true aquatic. In general, aquariums with live plants require more light than those without, but most standard aquarium hoods will grow aquarium plants. Some plants, such as the cryptocorynes and anubias, will do well with low light.

Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).
The main parts of a plant include: Roots. Stem. Leaves.
Answer: Only a few plants, such as lotus and water lilies, have roots that fix the plants in the mud at the bottom of the pond. They are known as fixed aquatic plants. The roots of such plants are fixed in the soil at the bottom of the pond.
