Question

Answer

Lichen is symbiotic association between algae and fungi ....hence B is correct

Answer

The correct answer is B

Answer

Option B is correct answer for questions

Answer

Algae and Fungi

Answer

Yes this is correct answer

Answer

S right option is b .Algee have chlorophyll .fungi didn't have chlorophyll so algee make food and give to fungi .fungi gives e
water minerals form roots to algee. so here living two members this is called linches .so option b is right

Answer

Option b is right

Answer

Introduction:
Lichen is a unique organism that is formed by the symbiotic association between algae and fungi. It is commonly found growing on rocks, trees, and soil surfaces. Lichen is considered as a pioneer organism and can survive in harsh environments such as deserts, mountains, and Arctic regions.

Explanation:
Lichen is composed of two main components - algae and fungi. Let's understand the role of each component in this symbiotic relationship.

1. Algae:
Algae are photosynthetic organisms that belong to the plant kingdom. They contain chlorophyll, a pigment that enables them to convert sunlight into energy through the process of photosynthesis. In the case of lichen, algae provide the necessary nutrients and energy to the partnership through photosynthesis. They produce organic substances such as carbohydrates, which are utilized by both algae and fungi.

2. Fungi:
Fungi are non-photosynthetic organisms that belong to a separate kingdom. They do not contain chlorophyll and cannot produce their own food through photosynthesis. In the case of lichen, fungi provide a protective structure for the algae. They form a network of filaments called hyphae, which create a mesh-like structure that protects the algae from desiccation and harsh environmental conditions. Fungi also absorb and retain water, which is essential for the survival of the partnership.

Symbiotic Relationship:
The association between algae and fungi in lichen is a mutualistic relationship. Mutualism is a type of symbiotic relationship where both partners benefit. In the case of lichen, algae provide the necessary nutrients and energy through photosynthesis, while fungi provide a protective structure and absorb water. This partnership allows lichen to survive in environments where neither algae nor fungi could survive independently.

Diversity of Lichen:
Lichen exhibits a wide range of forms and colors. This diversity is a result of the different species of algae and fungi that can form lichen. The exact species of algae and fungi present in lichen can vary depending on the environmental conditions. This allows lichen to adapt to different habitats and thrive in a variety of ecological niches.

Conclusion:
Lichen is a unique symbiotic association between algae and fungi. This partnership allows lichen to survive in harsh environments and play a crucial role in ecological processes such as soil formation and nutrient cycling. Understanding the symbiotic relationship between algae and fungi in lichen helps us appreciate the remarkable adaptability and resilience of these organisms.
