The reproductive part of the angiosperms are located in the flower. State the changes that takes place in the flower after the germinated pollens reach the ovules.?

Question

Answer

Pollen contains  two male gametes from which one fuses with female gamete present in ovule and other fuses with their polar nuclei. the polar nuclei then converted into endosperm which provide nutrition to ovule  which become zygote and zygote multiply and form embryo later. this embryo then form as a seed and endosperm provide nutrients to it and the ovary become fruits and all others parts of flowers fall down.

Answer

Changes in the Flower after Pollination:

- Fertilization:
After the germinated pollen reaches the ovules, fertilization occurs. This is when the sperm from the pollen combines with the egg in the ovule to form a zygote.

- Formation of Embryo:
The zygote develops into an embryo within the ovule. This is the beginning of seed formation in the flower.

- Development of Seed:
As the embryo grows, it is surrounded by nourishing tissues that will eventually become the seed. The ovary of the flower also develops into a fruit to protect the developing seed.

- Maturation of Seed:
Over time, the seed within the fruit matures. The fruit may change color, size, and texture as it reaches maturity, signaling that the seed is ready for dispersal.

- Seed Dispersal:
Once the seed is mature, the fruit may undergo various methods of dispersal such as being carried by animals, floating on water, or being spread by wind. This allows the seed to be transported away from the parent plant to grow in a new location.

- Growth of New Plant:
When the seed finds a suitable environment, it germinates and grows into a new plant. This marks the completion of the reproductive cycle of the angiosperm.
