About this previous year paper
This question paper evaluates fundamental concepts of microbiology, cell biology, infectious diseases, photosynthesis, viral multiplication, metabolic pathways, and human health.
It is divided into three sections testing definitions, short explanations, diagrams, and descriptive answers.
SECTION – A (7 × 2 = 14 Marks)
This section contains seven short-answer questions, requiring brief definitions or differences.
Topics include:
Domain bacteria
Gram-positive vs gram-negative bacteria
Types of bacterial cells
Amphibolic pathway
Vaccine
Natality and mortality
Differences between bacteria and archaea
This section checks basic biological terminology and core microbiology concepts.
SECTION – B (5 × 7 = 35 Marks)
Students must attempt any five descriptive questions, some requiring diagrams.
Topics include:
Types of microorganisms (bacteria, fungi, protozoa, algae, viruses)
Eukaryotic cell diagram
Sexually transmitted diseases
Light and dark reactions of photosynthesis
Stages of viral multiplication
Importance of microorganisms in medicine
AIDS and its mode of transmission
Detailed diagram and explanation of animal cell
This section tests concept understanding, biological processes, disease knowledge, and diagram-based learning.
SECTION – C (2 × 10.5 = 21 Marks)
Students must attempt any two long-answer questions.
Topics include:
Cancer
Meaning, causes, types, and modes of treatment (chemotherapy, radiation, surgery, immunotherapy)
Metabolic Diversity
Types of metabolism in microorganisms (autotrophic, heterotrophic, chemotrophic, phototrophic)
Krebs Cycle (TCA Cycle)
Steps, enzymes, energy yield, and significance
This section evaluates deep biological understanding, long explanations, and conceptual clarity.
