Respiration in Plants
Respiration in plants is studied to understand all the processes and steps involved in them that result in the utilization of organic compounds and the synthesis of energy. The first stage is glycolysis, in which glucose produced during photosynthesis is converted into pyruvate. The second stage is the Krebs cycle, which completes the breakdown of pyruvate, producing electron carriers, i.e., NADH2 and FADH2. ETC (electron transport chain), the final stage, generates ATP through the transfer of electrons while using the proton pump. Additionally, anaerobic respiration pathways like fermentation generate ethanol in microbes, and the lactic acid pathway takes place in muscle cells under stress. Understanding respiration in plants provides information on how they utilize stored energy for growth, development, and overall metabolic activities.
Plant Physiology
Plant Physiology is the study of plants that helps us to understand all the complex mechanisms that are occurring within the plant’s body. These complex mechanisms like photosynthesis, transport of water and nutrients, cellular respiration, etc. govern the plant’s life which we study under the specialized branch of plant physiology. Plant physiology involves understanding chlorophyll, stomatal regulation, the influence of hormones on growth, and other metabolic mechanisms driving plant life.
By investigating the role of environmental factors and stress responses, Plant physiology helps us to study and understand the resilience and adaptability inherent in the botanical world, offering insights into the fascinating interplay between plants and their surroundings.
