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) Release of male gametes.

Answer 1

Hint: A germ pore is a little pore in the external mass of the contagious pore from which then the germ tube exits upon germination. On the off chance that its area is thought of, at that point it tends to be apical or unconventional. Germ pore assumes a key part in the plant preparation.

Complete answer:
Germ pore: A germ pore is a little pore in the external mass of a contagious spore through which the germ tube exits upon germination. It tends to be apical or flighty in its area, and, on light microscopy, might be pictured as a lighter hued region on the cell divider.
Function of germ pore: The germ pores are gaps in the outcast layer of the dust grain. Where the sporopollenin is missing. The dust grain is a meager walled zone through which the germ cylinder (or) dust tube rises on germination. It serves to the development of the dust cylinder and delivers the male gamete during treatment.

Thus, the option (C) is correct.

Note: At least one slim zone present in the exiled of dust grains are known as germ pores. The germ pores are gaps in the exile layer of the dust grain where the sporopollenin is missing. The germ pore helps in the development of the dust tube and the arrival of the male gametes during preparations.
