Plant Physiology, Abiotic Stess
- Introduce the topic with the help of an extract from a video lecture that introduces the topic of plant physiology and abiotic stress in plants. It explains how plants respond to these stresses phenotypically and physiologically.
- The suggested video extract can be viewed from the beginning of the video till 27 minutes of the full -length video lecture (~78 min).
- Following the introduction, teachers can choose to use either one or both of the teaching tools in next twi sections to discuss plant responses to abiotic stresses due to climate change related factors.
- Use this video lecture, 'BIOPL3420 - Plant Physiology - Lecture 28: Plant Stress Responses', to explain what plant stress is and to define abiotic stressors as the external factors that affect plant physiology.
- Then, list the factors that may affect plant growth and development by perturbing its physiology.
- Further, discuss the types of responses shown by plants due to changes in their environment like immediate responses, acclimation and adaptation.
- Use this tool to explore phenotypic plasticity in plants that enable them to extend their range or region of optimal growth.
- Finally, use the lecture to distinguish short term phenotypic plasticity from evolutionary adaptations exhibited by these plants in response to long term environmental changes.
