Vedclass · Answer

(C) The pollen tube is a tubular structure produced by the male gametophyte (pollen grain) after it lands on the stigma of a flower. Its primary function is to transport the male gametes from the pollen grain to the ovule located within the ovary. Therefore,the growth of the pollen tube must continue until it reaches the ovule. Consequently,the total length of the pollen tube is determined by the distance it must travel from the point of germination (the upper surface of the stigma) to the target (the ovule).
