Similarities between sexual reproduction in flowering plants and animal

  • Gamete formation
  • Start from germ cells/unfertilized sell
  • Gamete formation is by meiosis
  • More than one male gamete is formed from one germ cell
  • Male and female gametes are haploid
  • Male gametes are smaller than female gametes
  • Gamete transmission

  • Fertilization
  • Syngamy (fusion of nuclei) occurs
  • Only one male gamete fuse with an ovum to forms single embryo
  • Male gametes digest their way through the walls of the ovum
  • Development and production
  • The embryo is nourished through the same embryo sac
  • Offspring show variation from the parents

  • Most animals are dioecious whereas most plants are monoecious

  • In plants, male gamete reaches ova by developing tubes, but male gametes in animals ae motile.
  • In plants, double fertilization occurs which does not occur in single animals
