1.	Question : (a) Draw an L.S. of pistil showing pollen tube entering into the embryo sac. Label the following : (i) Nucellus(ii) Antipodals(iii)Synergids(iv) Micropyle(b) Write the functions of the following :(i) Synergids(ii) Micropyle
Answer» Solution : (b) (i) Synergids : Synergids have special cellular thickenings at the MICROPYLAR tip called FILIFORM apparatus which plays an important ROLE in guiding the pollen tube into the SYNERGID. (b) Micropyle : It helps pollen tube to enter the ovule and then enters one of the synergids through the filiform apparatus.
