State the importance of the following response

a) Chemo-taxis in pollen grains

Answer and Explanation:

Chemotaxis occurs when an organism moves toward a certain direction in response to a chemical.

Pollen is essential for the reproduction of plants because it produces a pollen tube that moves the sperm cells to the ovules that are located in the interior part of the flower. The pollen grains, produced in the anthers of a plant, contain the male sex cells that will be transferred. Chemotaxis plays a central role as it is a process in which chemical extracellular signals enable the movement of the pollen grains that will eventually enable plant reproduction.
