NEET BIOLOGY

Detailed explanation-1: -In fungi, both asexual and sexual spores or sporangiospores of many fungal species are actively dispersed by forcible ejection from their reproductive structures. This ejection ensures exit of the spores from the reproductive structures as well as travelling through the air over long distances.

Detailed explanation-2: -Asexual Reproduction Almost all fungi reproduce asexually by producing spores. A fungal spore is a haploid cell produced by mitosis from a haploid parent cell. It is genetically identi ca l to the parent cell. Fungal spores can develop into new haploid individuals without being fertilized.

Detailed explanation-3: -Fungi have adapted to the problem posed by the boundary layer by either shooting their spores through it, or evading it entirely by utilizing vectors (animals or water or wind) for dispersal. Once spores are caught by the wind they can be carried very long distances.

Detailed explanation-4: -Fungi can reproduce asexually by fragmentation, budding, or producing spores, or sexually with homothallic or heterothallic mycelia.

Detailed explanation-5: -Most fungi reproduce by forming spores that can survive extreme conditions such as cold and lack of water. Both sexual meiotic and asexual mitotic spores may be produced, depending on the species and conditions.
