FAQs on Biological classification class 11 Chapter
Q1: What is the importance of biological classification?
Answer: Biological classification helps in the systematic study of organisms, understanding their relationships, and identifying evolutionary trends.
Q2: What is the basis of Whittaker’s Five Kingdom Classification?
Answer: Whittaker classified organisms based on cell structure, mode of nutrition, and body organization.
Q3: Why are viruses not included in any kingdom?
Answer: Viruses are acellular, do not exhibit life processes outside a host cell, and hence are not classified into any kingdom.
Q4: What is the difference between Kingdom Monera and Protista?
Answer:
Monera: Prokaryotic, unicellular, no membrane-bound organelles.
Protista: Eukaryotic, unicellular/multicellular, has membrane-bound organelles.
Q5: How to download handwritten notes for Chapter 2?
