Question

What is the importance of oxygen gas dissolved in water ? How is the carbon dioxide gas dissolved
helpful to the plants which live in water ?​

Answer 1

Answer:

Hello mate

Explanation:

Dissolved oxygen (DO) is one of the most important indicators of water quality. It is essential for the survival of fish and other aquatic organisms. Oxygen dissolves in surface water due to the aerating action of winds. Oxygen is also introduced into the water as a byproduct of aquatic plant photosynthesis.

In aquatic plants or plants that live in water use carbon dioxide gas dissolved in water for carrying out photosynthesis. So, we can say that stomata pores allow the movement of gases in and out of plant cells. Therefore, the gaseous exchange in plants takes place through the stomata in leaves and other green parts.

Answer 2

Answer:

Dissolved oxygen and carbon dioxide are vital for marine life. Marine plants use dissolved carbon dioxide, sunlight and water to make carbohydrates through the process of photosynthesis. This process releases oxygen into the water.
