During fertilization in angiosperms, after the pollen tube is guided into one of the synergids by the filiform apparatus, where does it release the two male gametes?
Options
- AInto the cytoplasm of the synergid
- BDirectly into the cytoplasm of the egg cell
- CInto the central cell
- DInto the intercellular space between the egg cell and the synergid
Correct answer
A. Into the cytoplasm of the synergid
Step-by-step solution
According to NCERT, during the events of double fertilization, the pollen tube enters the embryo sac through the micropylar end and is guided by the filiform apparatus into one of the synergids. Upon entry, the pollen tube releases the two male gametes into the cytoplasm of the synergid. From this location, one male gamete subsequently moves towards the egg cell to undergo syngamy, and the other moves towards the central cell for triple fusion. The gametes are not released directly into the egg cell, the central ce
