Option A, Blue green algae, acts as a bio-fertilizer for the rice crop. Blue-green algae, also known as cyanobacteria, establish a symbiotic relationship with rice plants, providing them with fixed atmospheric nitrogen. This process, known as nitrogen fixation, enhances soil fertility by increasing the availability of nitrogen to the rice plants. The nitrogen-fixing ability of blue-green algae reduces the need for synthetic fertilizers, thereby promoting sustainable agricultural practices. Rhizobium species (Option B) typically form symbiotic relationships with leguminous plants, aiding in nitrogen fixation in their root nodules. Mycelium (Option C) refers to the vegetative part of fungi and does not directly act as a bio-fertilizer for rice crops. Azotobacter (Option D) is a free-living nitrogen-fixing bacterium that can enhance soil fertility but is not commonly associated with rice cultivation as blue-green algae are.

The cell wall of fungi is primarily composed of Option [D], chitin and hemicellulose. Chitin, a strong polysaccharide, forms the major structural component, providing rigidity and support to fungal cells. Hemicellulose, another polysaccharide, contributes to the strength and flexibility of the cell wall. This unique composition distinguishes fungal cell walls from those of other organisms. Unlike plant cell walls, which contain cellulose, and bacterial cell walls, which contain peptidoglycan or other substances, fungal cell walls are characterized by the presence of chitin. This structural framework plays crucial roles in maintaining cell shape, protecting against environmental stresses, and facilitating nutrient uptake. Additionally, the composition of fungal cell walls influences interactions with other organisms and environmental factors, contributing to their ecological roles and impact on various ecosystems. Overall, chitin and hemicellulose are key components that define the distinctive architecture and function of fungal cell walls.

Fungi store reserved or accumulated food substances primarily in the form of glycogen. Glycogen, a polysaccharide composed of glucose units, functions as a readily available energy source. It serves as a storage molecule for excess glucose produced during periods of plenty. When energy demand rises, fungi break down glycogen through glycogenolysis, releasing glucose molecules for energy production via cellular respiration. Unlike plants, fungi lack chlorophyll and cannot perform photosynthesis to synthesize glucose from carbon dioxide and water. Instead, they obtain organic compounds from their surroundings or through symbiotic relationships. Glycogen storage enables fungi to thrive in diverse environments by providing a means to sustain metabolic activities during periods of nutrient scarcity. Additionally, some fungi may store lipids as oil bodies or accumulate starch granules, but these forms are less common compared to glycogen storage, which remains essential for their survival and growth.

All fungi are always heterotrophs. They lack the ability to produce their own organic compounds through photosynthesis. Instead, they obtain nutrients by absorbing preformed organic matter from their environment. While some fungi are parasitic, obtaining nutrients from living organisms, others are saprophytes, decomposing dead organic matter. Regardless of their lifestyle, fungi depend on external sources of organic carbon for energy and growth. This reliance on external nutrients distinguishes them from autotrophs, which can synthesize their own organic compounds using inorganic sources such as carbon dioxide and water. As heterotrophs, fungi play crucial roles in ecosystems by participating in nutrient cycling and decomposition processes, breaking down complex organic matter into simpler compounds that can be recycled and utilized by other organisms. This metabolic strategy enables fungi to thrive in diverse habitats and contribute to the balance of ecosystems worldwide.

Mycorrhizae have a symbiotic relationship with the roots of higher plants. This mutualistic association benefits both partners: the fungi aid in enhancing the plant’s nutrient uptake, particularly phosphorus and nitrogen, from the soil, while the plants provide the fungi with organic compounds derived from photosynthesis. Through this symbiosis, mycorrhizae contribute significantly to the health and productivity of terrestrial ecosystems. The fungal hyphae extend the surface area of the plant roots, facilitating greater access to soil resources, especially in nutrient-poor environments. In return, the plant supplies the fungi with carbohydrates synthesized through photosynthesis. This partnership is crucial for plant growth, stress tolerance, and ecosystem stability. Mycorrhizal associations are widespread in nature, occurring in a variety of ecosystems worldwide, and play a vital role in nutrient cycling, soil structure formation, and plant community dynamics. Overall, mycorrhizae exemplify the intricate and mutually beneficial relationships that characterize many biological interactions in nature.
