Similarities and differences between sexual reproduction in flowering plants and animal
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
- Male gamete moves towards an ovum by chemical attraction
- 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
Differences between sexual reproduction in flowering plants and animal
- Most animals are dioecious whereas most plants are monoecious
- In plants, reproductive organs are temporary but in animals are permanent and function throughout their lives
- In plants, male gamete requires an agent whereas in animals there is copulation
- 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
