A1: The best way is to study NCERT concepts thoroughly, practice topicwise MCQs regularly. Solving previous year MCQs and mock tests can boost accuracy and speed.
Q2: Are NCERT questions enough for Class 11 Biology MCQ-based exams?
A2: NCERT forms the base for all CBSE Physics MCQs. However, for better preparation, students should solve additional MCQs from reference books and practice HOTS and competency-based questions to develop better understanding.
Q3: Where can I find chapterwise Class 11 Biology MCQ questions with answers?
A3: You can find chapterwise MCQ questions with answers and detailed explanations on trusted educational platforms like xamcontent.com and physicsgurukul.com. These cover both basic and advanced-level questions.
Q4: Do CBSE Class 11 exams include MCQs?
A4: Yes, as per the latest CBSE exam pattern, objective questions, including MCQs, are part of the final exam paper. MCQs test conceptual understanding and application skills.
Q5: How to score high in Class 11 Biology MCQs?
A5: To score high, understand the theory from NCERT, solve a variety of MCQs (basic and conceptual), and regularly revise theory. Avoid guesswork and focus on time management during tests.
Q6: Define taxon. Give some examples of taxa at different hierarchical levels.
A6: Each unit or category of classification is termed as a taxon.
The different hierarchical levels starting from the basic level is species, followed by genus, family, order, class, phylum or division and kingdom.
Examples include,
(i) Insects represent a category of phylum-Arthropoda.
(ii) Taxon of bacteria is Monera.
(iii) Sponges form the taxon Porifera.
Q7: Why are living organisms classified?
A7: There are millions of living organisms on earth. All these living organisms differ in shape, size, color, habitat and many other characteristics. To understand their origin, diversity, distribution and inter relationship, the scientists have devised mechanisms to classify all of them. Classification of living organisms help in revealing the relationship between various organisms. It also helps in making study of organisms easy and organised.
Q8: What do we learn from identification of individuals and populations?
A8: Identification of individuals and populations helps the scientists to classify organisms in various categories. It helps to determine their exact place or position in the set plan of classification.
