Symbiosis

Plant symbiosis refers to mutually beneficial relationships between plants and other organisms. Examples include mycorrhizal associations with fungi, where plants exchange nutrients with the fungi, and nitrogen-fixing bacteria in root nodules that help plants acquire nitrogen. These symbiotic relationships enhance plant growth and health.

Plant symbiosis encompasses various mutually beneficial relationships between plants and other organisms. Examples include:

1. **Mycorrhizal Symbiosis:** Plants form partnerships with fungi (mycorrhizae) to enhance nutrient uptake. The fungi aid in the absorption of water and nutrients, while the plants provide sugars to the fungi.

2. **Nitrogen-Fixing Symbiosis:** Certain plants, like legumes, host nitrogen-fixing bacteria in their root nodules. These bacteria convert atmospheric nitrogen into a form that plants can use for growth, benefiting both partners.

3. **Rhizobium-Legume Symbiosis:** Leguminous plants engage in a symbiotic relationship with Rhizobium bacteria. The bacteria help fix nitrogen, contributing to soil fertility, and receive sugars from the plant.

4. **Endophytic Symbiosis:** Some plants host endophytic fungi or bacteria inside their tissues. These microorganisms can enhance plant resistance to stress, pathogens, and pests.

These symbiotic relationships contribute to plant health, nutrient acquisition, and overall ecosystem functioning.
