Mysterious events between the time the flower withers and the time the seed matures
An ovary grows big gradually after pollination and fertilization.
Let's record the date of flower opening and examine the development of a seed in sequence.

For us, watching flowers is a pleasure. But for the plants, flowers play an important role.
That role is to create new life.
A lot of new life comes from just one seed.
Let's examine a seed that holds life until the next year.
Appearance of a pistil and 5 stamens in a flower bud (left) and in an opened flower (right).
Moreover, let's watch what happens to them after the flower withers up.
If you have a microscope, use it to magnify and observe pollen.
It will be interesting to compare the pollen of the morning glory with that of another plants.
Let's compare differences between the structure of a pistil and the structure of stamens.
