Question

What are the post fertilization changes in the flower?

Answer 1

Post-fertilization changes in the flower

1. After the process of fertilization, the embryo undergoes a number of mitotic divisions to form a multicellular embryo.
2. The endosperm nucleus also goes through a series of divisions to form a mass of endosperm cells.
3. These endosperm cells provide nutrition to the developing embryo.

After fertilization, the following changes are observed in a flower:

1. There is the formation of a diploid zygote and it develops into an embryo, which forms the future plant.
2. The endosperm cells serve as a source of nutrition for the developing embryo.
3. The ovule becomes the seed.
4. The ovary becomes the fruit.
5. In most plants, the antipodals and synergies disintegrate before, during, or immediately after fertilization.
6. The outer and inner integuments of the ovule become the testa or the seed coat of the seed.
7. Petals and sepals fall off.
