Answers
Answer:-
The aquatic plants can be divided into four groups, they are:
- algae
- floating plants
- submerged plants
- emergent plants
- 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.
Example: lyngbya and muskgrass.
- Floating plants:
Floating plants are not attached to the water's bottom, but they have roots which absorb water. Floating plants can be found in fresh or salt water.
Example: water lilly
- Submerged plants:
Submerged or submersed plants are rooted to the water's floor and most of their vegetation is under water. The leaves of these plants are thin and narrow.
Example: hydrilla
- Emerged plants
Emerged plants (also known as emersed) are rooted to the ground of the water but have most of their vegetation above water. These plants need constant exposure to sunlight.
Example: knotweed
