Why do many mangrove plants possess high level of organic solutes?

Explanation

**Step-by-Step Solution:**

1. **Understanding Mangrove Plants**: Mangrove plants are a type of halophyte, which means they thrive in saline (salty) environments, typically found in coastal areas where saltwater meets freshwater.

2. **Salinity and Osmotic Potential**: In saline conditions, the concentration of salts in the surrounding water is high. To survive in such environments, mangrove plants need to manage the osmotic pressure. They do this by accumulating organic solutes within their cells.

3. **Role of Organic Solutes**: The high levels of organic solutes in mangrove plants help to create a higher osmotic potential in their roots compared to the surrounding saline water. This means that the concentration of solutes inside the plant cells is greater than that in the external environment.
