Vedclass · Answer

(D) The growth of the pollen tube towards the ovule is a classic example of $Chemotropism$. This occurs because the ovule releases specific chemical substances that act as a signal for the pollen tube. The pollen tube senses these chemicals and grows in the direction of the higher concentration of these substances,which leads it directly to the ovule for fertilization.
