What does a pollen grain form after germinating on the stigma?
Answer and explanation
Correct answer: Pollen tube
After landing on a compatible stigma, a pollen grain germinates and produces a pollen tube. The tube grows through the style toward the ovule and carries the male gametes to the embryo sac. The ovule later develops into a seed, the ovary into a fruit, and the zygote into an embryo. Therefore, pollen tube is the immediate product asked for here.
