Question
Chapter 22, Problem 3CT
Summary Introduction
To explain: The reason that the fruit tree does not need to make as much pollen as a pine to ensure pollination.
Introduction: The arrival of pollen grains on the female reproductive part of a seed plant is called pollination. Pollination can occur through wind, insects, or animals, or through water. This increases the genetic diversity of an organism.
