Overview of Plant Physiology
Plant physiology is a branch of biology that focuses on the functions and vital processes of plants. It encompasses various aspects of plant life, including:
1. Photosynthesis: The process by which plants convert light energy into chemical energy.
2. Respiration: The biochemical process where plants convert glucose into energy.
3. Transpiration: The movement of water within a plant and its evaporation from aerial parts.
4. Nutrient Uptake: The absorption of essential minerals and nutrients from the soil.
5. Growth and Development: The processes that determine how plants grow and develop over time.
The Introduction to Plant Physiology 4th Edition serves as a bridge connecting these fundamental concepts with practical applications in agriculture, horticulture, and environmental science.
