Chapter 23, Problem 16A

Summary Introduction

Introduction :

Flower is the most beautiful part of a plant. The colours, shapes, and sizes of flowers are determined by the genetic makeup of each species. Flowers can vary in structure and form from species to species. A flower has many organs. Some organs provide support and protection, whereas others can be involved directly in the reproduction process. In general, flowers have four organs. They are sepals, stamens, petals, and pistils.
