Plant physiology involves the study of plant functions and processes from "summary" of NCERT Solutions - Biology for Class 12th by Dr. Madhurbhashini,Sargam Hans,Shanya Hans
Plant physiology delves into the intricate workings of plants, exploring their various functions and processes. One of the key aspects of plant physiology is understanding how plants absorb water and nutrients from the soil, a crucial process that sustains their growth and development. Through the study of plant physiology, scientists gain insights into how plants transport these essential resources from their roots to other parts of the plant, such as the leaves and flowers. Another important area of study in plant physiology is photosynthesis, a process through which plants convert sunlight into energy. This process not only allows plants to produce their own food but also plays a vital role in the Earth's ecosystem by releasing oxygen into the atmosphere. By delving into the mechanisms of photosynthesis, researchers can uncover how plants capture sunlight, absorb carbon dioxide, and produce glucose, the primary source of energy for plants. Plant physiology also encompasses the study of plant responses to external stimuli, such as light, temperature, and hormones. Understanding how plants react to changes in their environment provides valuable insights into how they adapt and survive in various conditions. For example, researchers study how plants respond to changes in light intensity by adjusting their rate of photosynthesis or how they adapt to fluctuations in temperature by altering their metabolic processes.- Plant physiology explores the mechanisms behind plant growth and development, including cell division, differentiation, and tissue formation. By studying these processes, scientists can unravel the genetic and molecular mechanisms that regulate plant growth, shedding light on how plants develop from seeds into mature organisms. In essence, plant physiology serves as a foundation for understanding the fundamental processes that govern plant life and provide essential resources for all living organisms.
