Question

Explain the method of sexual reproduction in plants​

Answer 1

Answer:

Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit.

Answer 2

Answer:

Sexual Reproduction: In sexual reproduction new plants are produced from  seeds.

• Flowers are the reproductive parts of the plant.
• Stamen is the male  reproductive part and pistil is the female reproductive part.
• Flowers which have only the stamen or only the pistil are called  unisexual flowers. Eg :- Maize, Papaya, Cucumber etc.
• Flowers which have both the stamen and pistil are called bisexual  flowers. Eg :- Rose, Mustard, Petunia etc.
• The stamen has a filament and anther.
• The anther contains pollen  grains which contain the male gametes.
• The pistil has stigma, style and ovary.
• The ovary contains ovules  which contain the female gamete or egg.
• In sexual reproduction the male and female gamete fuse together to  form a zygote.

Pollination:

• The transfer of pollen grains from the anther to the stigma  of a flower is called pollination.
• Pollen grains are transferred by wind, water or insects.
• If pollen grains lands on the stigma of the same flower, it  is called self pollination.
• If pollen grains of one flower lands on the stigma of  another flower it is called cross pollination.

Fertilization:

• The process of fusion of the male and female gametes to  form a zygote is called fertilization.
• After fertilization the zygote develops into an embryo.
• The  ovule then develops into the seed and the ovary develops  into the fruit.

Seed Dispersal:

• The carrying away of seeds from one place to another is called  dispersal of seeds.
• Seeds are dispersed by wind, water and animals.
• Seeds dispersed by wind are light, have wings or hairs so that they  are easily blown away by wind. Eg :- drumstick. maple, sunflower, aak  etc.
• Seeds dispersed by water have spongy or fibrous outer cover so that  they can float on water. Eg :- coconut
• Seeds dispersed by animals have spines with hooks so that they can  attach to the bodies of animals. Eg :- xanthium
