The concept of species and its significance in classification and binomial nomenclature are also discussed.
• The fourth section covers the role of museums, zoos, herbaria, and botanical gardens in studying taxonomy, the importance of specimen collections, and their preservation. Techniques for collecting, preserving, and studying specimens are also introduced.
• The fifth section covers an overview of the five kingdom classification system: Monera, Protista, Fungi, Plantae, and Animalia.

You will learn about the three to five distinguishing features and examples of each category. The detailed study of Angiosperms: classification up to class, characteristic features, and examples is also included in this section.
• The seventh section covers the salient features and classification of non-chordate animals up to phylum level, and the salient features and classification of chordate animals up to class level. Examples of each phylum and class with their characteristic features are also discussed.
