AP BIOLOGY

Detailed explanation-1: -haploid spores are produced after meiosis that produce gametophytes. In algae and fungi, true asexual spores are produced by mitosis that germinates and produces new offspring.

Detailed explanation-2: -3.1 Asexual spores. Asexual spores are formed after mitosis (mitospores) without the involvement of meiosis. Fungi produce an enormous variety of asexual spores.

Detailed explanation-3: -Spores are produced by mitosis in spore mother cells present in sporangia in pteridophytes.

Detailed explanation-4: -In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes.

Detailed explanation-5: -Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants.
