Examples
- The germ pore is a critical structure in the germination process of fungal spores, allowing the germ tube to emerge and initiate growth.
- During pollen germination, the germ pore serves as the point of exit for the pollen tube, which then grows towards the ovary.
- In some species of fungi, the germ pore is surrounded by a specialized ring of material that helps to regulate the emergence of the germ tube.
- The location and structure of the germ pore can vary significantly between different types of spores and pollen grains.
- In the process of germination, the germ pore is the first point of contact between the emerging germ tube and the external environment.
