Plant physiology is the study of how plants function and respond to their environment. It involves understanding the various physiological processes and mechanisms that occur within plants, allowing them to grow, develop, reproduce, and adapt to different conditions. Here are some key areas of plant physiology: 1. Photosynthesis: Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a sugar) and oxygen. It occurs in the chloroplasts of plant cells and is crucial for plant growth and the production of oxygen in the atmosphere. 2. Respiration: Plant respiration is the process through which plants break down glucose to release energy for their metabolic activities. It occurs in all living plant cells, including during photosynthesis, and involves the consumption of oxygen and the production of carbon dioxide. 3. Transpiration: Transpiration is the loss of water vapor from plant leaves and stems through small openings called stomata. It hel...
