NEET BIOLOGY

Detailed explanation-1: -Fungi reproduce by spores, which are produced by either sexual or asexual methods, and the majority of fungal spores are adapted for airborne dispersal. Spores may originate from fungal saprobes, pathogens, or symbionts.

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: -The spores may be released actively or passively. In the former the fungus, through its own actions, ejects the spores from the basidia or asci with considerable force. In the latter the fungus relies on some other agent to release the spores from the fruiting body. The agents are varied-wind, impact, water, insects.

Detailed explanation-4: -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. Most fungi life cycles consist of both a diploid and a haploid stage.

Detailed explanation-5: -Spores are easily picked up by air currently, animals, or other physical objects that brush past or come into contact with them. This contact enables the spores to spread and create new mold colonies. In our homes, spores become airborne when we try to clean up mold or disturb it in some way.
