Questions

Which syllabus does this course follow?

It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc Botany, Semester 5. Where your own university's syllabus differs, the centre follows your university's syllabus and question pattern.

Is there a practical for this paper?

Yes. Experiments in Plant Physiology and Molecular Biology (same semester) covers osmosis, transpiration, photosynthesis and enzyme experiments.

Is there a test after the course?

Yes. Unit-wise multiple-choice tests and a final exam paper are included for semester exam practice.
