Question
Chapter 40.3, Problem 1CC
Summary Introduction
To determine: The maximum number of cells in a mature male gametophyte of a flowering plant.
Introduction: The reproductive part of a plant is its flower. Male gametophyte is represented by the pollen grain. The transfer of male gamete from the anther to stigma is known as “pollination.” The fusion of gametes rsepresents the process of “fertilization.”
