Functions of Synergids

Ultra structurally the structure and concentration of cell organelles reveals that synergids are metabolically active. The following Wee functions are attributed to synergids.

1. Directing of pollen tube growth by secreting some chemotropically active substances.

2. The degenerating synergids form the site for pollen tube discharge in the embryo sac.

3. The filiform apparatus may aid in the absorption and transportation of materials into the embryo sac from the nucellus.
