Answer 1

burst and form a tiny tube

explanation:

Only after pollination, when pollen has landedon the stigma of a suitable flower of the same species, can a chain of events happen that ends in the making of seeds. A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary. The ovary develops into a fruit to protect the seed.
