Understanding the Germ Pore
The germ pore is a crucial structure found in the pollen grain, specifically at one of its poles. Its primary function is associated with the fertilization process in plants.
Key Functions of the Germ Pore:
- Initiation of Pollen Tube:
The germ pore serves as the exit point through which the pollen tube emerges. When a pollen grain lands on a compatible stigma, it absorbs moisture and swells. This swelling triggers the germination of the pollen grain.
- Pollen Tube Growth:
Once the pollen tube begins to emerge from the germ pore, it elongates down the style towards the ovule. This growth is critical for the delivery of male gametes to the ovule for fertilization.
- Fertilization Process:
The pollen tube carries two sperm cells that travel through the style and reach the ovule, where fertilization occurs. This process is essential for seed development and the continuation of plant species.
Conclusion:
The germ pore is vital in the reproductive cycle of flowering plants. By facilitating the emergence of the pollen tube, it ensures the successful transfer of male gametes to the ovule, thereby playing a key role in fertilization. Thus, option 'C' - "Initiation of pollen tube" is the correct answer.
