similarity 1:

similarity 2:

difference 1:

difference 2:

difference 3:

Answer 1

• Both plants and humans with produce the sex cells, through meiosis, and produce haploid reproductive cells, during their life cycle.
• Both posses a fertilization stage, in which they produce a embryo, which will develop into an individual.

• Plants can survive in both haploid and diploid stage, but human can survive only in diploid stage.
• Life cycle of plants divided into sporophyte stage and gametophyte stage, no such division in humans.
• Plants life cycle starts from seed, whereas animal life cycle starts with fertilization.
