The concept of the Three Domains of Life – Archaea, Bacteria and Eukarya is a crucial part of Class 11 Biology NCERT Chapter The Living World. This classification, proposed by Carl Woese, helps students understand evolutionary relationships and major differences between cell types. To prepare effectively for CBSE exams and NEET-UG, we bring you a set of CBSE Class 11 Biology MCQs Three Domains of Life designed strictly as per the NCERT syllabus. These objective questions cover the unique features of prokaryotes and eukaryotes, extremophiles in Archaea, bacterial diversity, and the complexity of Eukarya. With an online practice test featuring automatic scoring and per-question feedback, students can instantly evaluate their knowledge, identify weak areas, and improve accuracy. This resource is ideal for quick revision, self-assessment, and ensuring exam readiness for both CBSE board examinations and NEET aspirants.
