What is the function of germ pores?
Absorption of water for seed germination
Initiation of pollen tube
Release of male gametes
The emergence of radicle
Germ pores are prominent apertures in the pollen grain's exine where the resistant organic material sporopollenin is absent . Following compatible pollination, the pollen grain germinates on the stigma, and a pollen tube emerges through one of these germ pores to transport male gametes toward the ovary .
