Why would cross fertilization happen more if the stamen and pistol matured at different times?

Question

im so lost can you explain it to me?

THANKS

Answer 1

Because the plant would not have the ability to self-polinate if it did not have both its stamen and pistol at the same time (the stamen and pistol are for plants much like human reproductive organs are for us- you need both for reproduction)

Lacking both a stamen and pistol, the only way a plant can reproduce is with another plant.
