Question
Chapter 30, Problem 11TYK
Summary Introduction
Introduction: Pollinators are creatures such as bees, butterflies, birds, beetles, and small mammals that are involved in pollinating the plant. The pollinators carry the pollen from the male anther to the female stigma of a flower. This facilitates the fertilization of ovules in the flower by the male gametes, which were carried out by the pollen grains.
