Question

trace the sequence of steps after germination of pollen grain on the stigma till fertilization (write 4 steps for your answer)​

Answer 1

Answer:

So let's review. plant fertilization is the joining of male and female gametes, resulting in a zygote. The most generalized form of this process requires four steps: pollination, germination, penetration of the ovule, and fertilization. After fertilization, the zygote divides to form an embryo.

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. ... The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant.
