Practice Questions
| Number | Name | Type | Difficulty | Marks | Description |
|---|---|---|---|---|---|
| 1. | Exploring the Invisible World through different objects | Other | easy | 2 m. | This question focuses on how instruments help us observe objects that are not visible to the naked eye. |
| 2. | Lens and Magnifying Glass | Other | medium | 2 m. | This question assesses how lenses bend light to enlarge and make objects appear clearer. |
| 3. | Compound microscope vs Electron microscope | Other | medium | 2 m. | This question compares different types of microscopes based on their magnification and usage. |
| 4. | Dyes used in cell study | Other | easy | 1 m. | This question describes the role of stains like methylene blue and safranin in making cells visible under a microscope. It explains how dyes improve contrast to observe cell structures clearly. |
| 5. | Label the parts in plant and animal cell | Other | medium | 3 m. | This question describes identifying and labeling key parts in plant and animal cell diagrams. It strengthens understanding of cell structure through visual learning. |
| 6. | Variation in Cell Size and Function | Other | easy | 1 m. | This question emphasises how differences in cell size influence their efficiency and ability to perform specific functions in living organisms. |
| 7. | Cells to Organism | Other | medium | 5 m. | This question emphasises how cells organise into tissues, organs, and systems to form a complete organism. |
| 8. | Cell Theory and the Origin of Multicellular Life | Other | hard | 5 m. | This question emphasises how cell theory explains the formation, growth, and continuity of life in multicellular organisms. |
| 9. | Cell and Microorganisms Variation | Other | easy | 2 m. | This question focuses on how variation in cell structure extends to microorganisms, where even a single cell can perform all life processes. |
| 10. | Structure, Diversity and Functional Roles of Bacteria | Other | hard | 5 m. | This question highlights the structure, shapes, and beneficial and harmful roles of bacteria in different environments. |
| 11. | TBQ - Fermantation of milk | Other | medium | 3 m. | This question focuses on how bacteria like Lactobacillus convert milk into curd through fermentation. |
| 12. | TBQ - Microorganisms in Agriculture | Other | hard | 5 m. | This question focuses on how bacteria like Rhizobium help in nitrogen fixation and improve soil fertility in agriculture. |
