- Cellular responses to environmental stimuli
📝 Examination Pattern & Assessment
The examination tests conceptual understanding, diagram drawing skills, and application of cellular principles. Questions assess knowledge of cellular structures, processes, and their significance in plant biology. Diagrams with proper labeling are essential for scoring high marks. Internal assessment includes practical exams and assignments.
🔬 Practical Component Details
Practical Examination: 25 marks (Separate from theory)
- Microscopic study of plant cells (onion peel, leaf epidermis)
- Study of cell division stages (mitosis in onion root tip)
- Preparation and observation of temporary mounts
- Study of different cell organelles through models/charts
- Measurement of cell size using micrometer
- Experiments on osmosis and plasmolysis
- Viva voce on practical techniques and observations
