NEET BIOLOGY

Detailed explanation-1: -They are called sac fungi because their sexual spores, called ascospores, are produced in a sac or ascus.

Detailed explanation-2: -The sexual spores, called basidiospores, are produced and forcibly ejected from a club shaped cell called a basidium. The developing basidium is the site of karyogamy and meiosis.

Detailed explanation-3: -The sexual spores form in the club-shaped basidium and are called basidiospores. In the basidium, nuclei of two different mating strains fuse (karyogamy), giving rise to a diploid zygote that then undergoes meiosis.

Detailed explanation-4: -Asexually, the hyphae of the sac fungi are divided by septa with pores, that is, they have perforated walls between adjacent cells [6]. They reproduce asexually by producing spores, called conidia, which are born on specialized erect hyphae, called conidiophores.

Detailed explanation-5: -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.
