Open in App
Solution
The correct option is C Chemotropism
Chemotropism is a type of growth response to a chemical stimulus. An example of chemotropic movement in plants can be seen during the growth of the pollen tube towards the ovules contained in the ovary. The ovary releases chemicals that produce a positive chemotropic response from the developing pollen tube. The pollen tube carries the male gametes. These male gametes reach the ovules through the growing pollen tube and then fertilization occurs.
Therefore, the correct answer is option A.
