Biology Question on sexual reproduction in flowering plants
Through which cell of the embryo sac, does the pollen tube enter the embryo sac ?
A
Egg cell
B
Central cell
C
Persistent synergid
D
Degenerated synergid
Answer
Degenerated synergid
Explanation
Solution
The pollen tube gains access to the embryo sac through the micropylar end, and it can directly penetrate either the synergid or the space between the egg cell and synergid. This process typically occurs through the degenerated synergid.
So, the correct option is (D): Degenerated synergid
