Germination of pollen on stigma is also known as female reproductive system in plants ??????? Pls answer fastttttttttttttttt

Answer 1

Answer:

Explanation:

The pollen germinate on the stigma and form pollen tube. The pollen tube carries two male gametes. The pollen tube may enter through micropyle(porogamy),chalazal end(chalazogamy) and through integuments(mesogamy). The pollen tube then enters the embryo sac. The first male gamete fuses with egg cell to form Zygote. This process is called SYNGAMY. The secondary male gamete fuses with the polar nuclei to form endosperm. This is called TRIPLE FUSION. Due the occurrence of 2 fertilization the process is called double fertilization.
