Growth of the pollen tube towards the ovule occurs due to what?

Answer and explanation

Correct answer: Due to chemical signals

The governing concept is chemotropism, in which growth is directed by chemical substances. During reproduction in flowering plants, chemical signals associated with the ovule and female tissues guide the pollen tube through the style toward the ovule, allowing the male gametes to reach the embryo sac. Light, gravity and touch are not the primary directional cues in this case. Therefore option B is correct, and the item also connects directly with plant reproduction.
