<-- On the left is the condition of the dead flower 2 to 3 days after it bloomed. Such dead flowers are often found in high temperatures.
1 When a flower is pollinated, a pollen tube grows and arrives at an ovule in an ovary in the basal part of a pistil. Finally, fertilization (conjugation of an egg cell in an ovule and a sperm nucleus from a pollen) occurs there. When a flower withers up, it means that fertilization of the flower is complete.
2 The appearance 2 to 3 days after fertilization.
3 You can see that the fertilized ovary grows and swells out for 1 week.
4 At about 2 weeks after fertilization, the ovary has grown very large. We call this a fruit.
<-- Side view of the ovary 2 to 3 days after fertilization. Judging from its outside, we can see that the ovary seems almost unchanged from the way it was before fertilization.

What happens after a flower withers up?
The basal (lower) part of a pistil swells day by day after the flower blooms. What happened?
Let's observe and study whether this swelling has any relation to the flower blooming or not.
