Question

Describe the events that take place between pollination and fertilization in plants.

Answer 1

Only after pollination, when pollen has landed on 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. This pollen tube carries a male gamete to meet a female gamete in an ovule. Once the pollen moves down the style, it reaches the ovules, that require sperm to fertilize them and produce new embryos.
