Question

What is the function of germ pore?

• A. Emergence of radicle
• B. Absorption of water for seed germination
• C. Initiation of pollen tube
• D. All of these

Answer 1

Answer: (C)

One or more thin areas present in the exine of pollen grains are known as germ pores. The germ pores are apertures in the exine layer of the pollen grain where the sporopollenin is absent. The germ pore helps in the formation of the pollen tube and the release of the male gametes during fertilisation. There are usually three germ pores in dicots (tricolpate) and one in monocots (monocolpate).
