Solution(By Examveda Team)
The cell of embryosac which releases one chemical to guide the movement of pollen towards the ovule is Synergids.Synergid cells are two specialized cells that lie adjacent to the egg cell in the female gametophyte of angiosperms and play an essential role in pollen tube guidance and function.
Defensin-like polypeptide LUREs are pollen tube attractants secreted from synergid cells.
