Answer:
Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.
Explanation:
In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.
Humans and ferns are similar as both fertilize to give rise to a new life while different as the haploid form of life present in the ferns life cycle and both male and female reproductive parts are present in one plant.
Life Cycle of fern:
- The diploid fern gives rise to haploid spores which grow and form a gametophyte plant in which the male and female reproductive systems present.
- Male gamete fertilizes with the female gamete to form a diploid spore (seed) which gives rise to a new fern.
Human’s reproductive cycle :
- Human is diploid animal and male and female are clearly distinguished.
- Male sperm fertilizes the female egg to form a zygote which gives rise to a new human.
Therefore, humans and ferns are similar as both fertilize to give rise a new life while different as the haploid form of life present in the ferns life cycle and both male and female reproductive parts are present in one plant.
