Question

Mention the change a flower under goesafter fertilisation

Answer 1

After fertilization the petals,stamen and carpel fall off and only sepal,ovary and ovule remain. This is because after fertilization the ovary develops into fruit and protect the seeds, these seeds are actually fertilized ovule. But, carpels and petals do not have any role after fertilization so they fall off. After fertilization, the outer layers of the ovule become impervious, hard and function as a seed coat. An ovule with an embryo inside is called a seed .
