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 gametes 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 because there is less risk of transferring the gametes as a result locomotion, internal fertilization and behaviors patterns such as courtship 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 require an agent whereas in animals there is copulation
• In plants, male gamete reaches ova by developing tubes, but male gametes in animals are motile.
• In plants double fertilization occurs which does not occur in single animals
