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.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
