Function of filiform apparatus is to
recognize the suitable pollen at stigma
stimulate division of generative cell
produce nectar
guide the entry of pollen tube.
In the diagram given below, show the path of a pollen tube from the pollen on the stigma into the embryo sac. Name the components of egg apparatus.
