Detailed explanation-1: -Sexual reproduction is similar in both plants and animals because it involves the fertilization of a female gamete by a male gamete in both organisms. A gamete is a sex cell that contains half the genetic information as somatic cells, which are all of the other cells in the body.
Detailed explanation-2: -The Ovule is like the egg in animals and once fertilization has taken place will become the seed. This is the flower’s attachment to the stalk and in some cases becomes part of the fruit after fertilization e.g. strawberry. Gives support to the flower and elevates the flower for the insects.
Detailed explanation-3: -In sexual reproduction new organisms are produced from the fusion of a male sex cell with a female sex cell. This fusion of gametes is called fertilisation. Sex cells are also known as gametes.
Detailed explanation-4: -Flowering plants reproduce sexually through a process called pollination. Flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. Pollen contains the male gametes.
