Hii mate, mate here is your answer.

What are Oxygenating Plants?

Submerged water plants are also known as oxygenating pond plants because they actually filter the pond water. Submerged plants also keep algae growth under control and provide oxygen. Submerged plants grow fully immersed in water and get their nutrients from the water through their leaves, not their roots like other plants. Plants that grow completely under water provide shelter for fish, oxygen to the water and filter out pollutants.

Hope this answer helps to you ☺️✌️
