AP BIOLOGY

Detailed explanation-1: -Meiospores: spores produced by meiosis; they are thus haploid, and give rise to a haploid daughter cell(s) or a haploid individual.

Detailed explanation-2: -spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes. The union of two gametes during fertilization produces a diploid zygote, which divides mitotically to form a new sporophyte.

Detailed explanation-3: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-4: -The sporophyte is diploid, but the spores are haploid. The spores disperse and germinate into new gametophytes, repeating the process (see Figure 1.4.

Detailed explanation-5: -Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
