Precisely in chapter 2 and meticulously in chapter 3, the classification of the plant kingdom has been discussed based on morphology and other characteristics. So, this chapter is a sub-part of the third chapter, and the morphology of flowering plants has been discussed here. To correctly understand the biology of any higher plant (or any other living organism) and to successfully classify them, appropriate knowledge about the standard technical/biological terms and definitions is a must.
It is also written that awareness about the plants' potential variants in different parts that are seen as altered or modified versions of the plants to their environments is crucial. For example, transformation to various habitats, for protection, storage, or climbing. Other topics included in this chapter are stem, roots, inflorescence, leaf, fruit, seed, flower, description of a stereotype flowering plant in a semi-technical language, and a description of some significant plant families and a few more. All the stated topics have been shortly elucidated below.
The above subtopics make chapter 5 of class 11 Biology syllabus complete where extensive knowledge about different parts of the flowering plants has been provided for students' comprehensive learning. Through this chapter, students will come across many variations of a flowering plant in terms of size, shape, mode of nutrition, structure, habit, habitat, and life span. It also peaches about the well-developed root and shoot systems of the flowering plant, particularly about the root system, which is either fibrous or taproot in nature.
Also presented are details on stem modifications and various terms linked with the morphology of flowering plants. The chapter also discusses ovules, which, after undergoing fertilization, grows into a seed. After this, the focus of the chapter moves to the types of seed and their structure. The important families of the flowering plant discussed here are Fabaceae, Liliaceae, and Solanaceae where the families' floral & vegetative characters and economic significance have been explained.
