Answer:
Similarities: 1) They both reproduce sexually by fertilization 2) They both have male and female reproductive parts
Differences: 1) Plants can either be monosexual or bisexual while humans are always bisexual
2) Plants employ double-fertilization while humans don't
Step-by-step explanation:
All organisms including plants and humans have to reproduce in order to produce young generations. However, there are similarities and differences between the reproductive cycles of these organisms. According to the question, we'll be comparing and contrasting reproduction in flowering plants and humans.
SIMILARITIES:
Both flowering plants and humans have sexual means of reproducing, which involves fusion of male and female gametes to produce a ZYGOTE, a process called FERTILIZATION.
Also, the opposite gametes that fuses during fertilization are produced by distinct male and female parts on both flowering plants and humans. For example, the anther produces the pollen containing the male gametes, while the ovary produces the egg cells in flowering plants. The testes and ovary produce the sperm and eggs in humans.
DIFFERENCES:
Flowering plants can either be monosexual i.e. bear both male and female reproductive structures on same plant or bisexual i.e bear the different reproductive structures on different plants. Humans are always bisexual i.e. they bear different reproductive structures depending on the sexuality.
A phenomenon unique to flowering plants called Double Fertilization occurs. This is a process whereby a triploid endosperm is formed from the fusion of two haploid nuclei with a sperm cell. This process only occurs in flowering plants and is absent in human reproductive cycle.
