Â
This course builds upon the foundation of Functional Botany–I of last semester III and explores how plants function at the physiological, anatomical, and molecular levels. It bridges the gap between structure and function in plants, helping learners understand how plants respond to environmental factors and internal signals.
The course aims to enable the learner to:
1. Â Â Gain knowledge of Photoperiodism and Vernalization in plants.
2. Â Â Learn about stress mechanisms that help plants survive adverse conditions.
3. Â Â Acquire knowledge of the internal morphology of plants.
4.   Understand proteins — their classification, types, structure, and function.
5. Â Â Explore the applications of plant anatomy in various scientific and industrial fields.
After successful completion of this course, the learner will be able to:
1. Â Â Describe the physiological processes of Photoperiodism and Vernalization.
2. Â Â Analyze how plants respond to and manage environmental stress.
3. Â Â Discuss the internal morphological features of plants and their significance.
4. Â Â Explain the classification, structure, and function of proteins in plants.
5. Â Â Understand and apply the anatomical principles in related fields like taxonomy, ecology, and pharmacognosy.
