CHAPTER 5 MORPHOLOGY OF FLOWERING PLANTS
THE ROOT The part of the plant that lies under the soil is called the root. The primary root bears lateral roots like secondary and tertiary roots, etc. The primary roots and its branches constitute the tap root system. THE STEM The stem is the ascending part of the axis bearing branches, leaves, flowers and fruits. THE LEAF The leaf is a lateral, generally flattened structure borne on the stem. It develops at the node and bears a bud in its axil. The axillary bud later develops into a branch. THE INFLORESCENCE A flower is a modified shoot wherein the shoot apical meristem changes to a floral meristem. The arrangement of flowers on the floral axis is termed as inflorescence. THE FLOWER The flower is the reproductive unit in the angiosperms. Parts of a flower:
THE FRUIT The fruit is a characteristic feature of the flowering plants. It is a mature or ripened ovary, developed after fertilization. THE SEED The ovules after fertilization develop into seeds. A seed is made up of a seed coat and an embryo.
