The petals and the stamens generally dry and fall off after fertilization. Why?
Answers
Answer:
After fertilization the sepals, petals and stamens of the flower wither and fall off. The pistil however, remains attached to the plant. The zygote develops into the embryo and the ovules develop into the seed.
In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination. Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel.
Different plant sections exhibit several sorts of alterations upon fertilisation:
The flower's sepal and stamen wither away.
The flower's sepal normally falls off after fertilisation, however in certain species it may continue to be connected.
To develop the fruit, the ovary in the flower thickens and grows.
The flower's ovule develops into the seeds.
Sepals and Petals wither and fall off after fertilization of the flower because they are no longer needed by the plant. The petals only serve the function to attract pollinators and protect the ovary, which is not needed after the formation of zygote inside the ovule.
