What is Plant Physiology?
Plant physiology is the scientific study of the functions and processes that occur within plants. It encompasses a wide range of topics including photosynthesis, respiration, nutrient uptake, hormone signaling, growth, development, and responses to environmental stimuli.
Key Areas of Study
- Photosynthesis: How plants convert light energy into chemical energy.
- Respiration: The metabolic process that releases energy from sugars.
- Water and Nutrient Transport: Movement of water and minerals through xylem and phloem.
- Plant Hormones: Chemical messengers like auxins, gibberellins, and cytokinins that regulate growth.
- Environmental Responses: How plants adapt to light, temperature, drought, and other stresses.
Why It Matters
Understanding plant physiology is essential for improving crop yields, developing stress-resistant varieties, conserving natural ecosystems, and addressing global challenges like food security and climate change.
