Plant Physiology MCQs

Plant physiology is the branch of botany focused on how plants function at cellular, biochemical, and organismal levels. It investigates crucial processes—photosynthesis, nutrient uptake, respiration, hormone action, and water transport—essential for plant growth, development, and environmental adaptation.

Key areas within the study of plant physiology include

1. Photosynthesis
2. Respiration
3. Transpiration
4. Water and mineral uptake
5. Transport (xylem and phloem)
6. Growth and development
7. Hormonal regulation
8. Nutrient assimilation
9. Stress physiology
10. Reproductive physiology

Photosynthesis: Plants capture light energy to convert carbon dioxide and water into glucose for energy,.
Water and Nutrient Transport: The xylem moves water upward from roots, while phloem transports nutrients throughout the plant.
Growth and Development: Study of how phytohormones regulate growth, seed germination, and response to environmental stressors like heat or drought.
Environmental Physiology: Understanding how plants adapt to their environment, such as managing water loss through stomatal closing
