Transportation in Plants
Transportation in plants, a part of plant physiology explores the complex systems that facilitate the movement of water, nutrients, and other substances within plants. It includes the Xylem, responsible for the upward water transport from roots to leaves, and the phloem, which transports organic nutrients like sugars throughout the plant. Transpiration, a critical process, involves the loss of water from plant surfaces, creating a negative pressure that aids in water ascent, called the ascent of sap. The adhesion-cohesion theory explains the mechanism behind water movement in plants from the root to the leaves and other regions of the shoot. Root pressure, osmosis, and capillary movement also contribute to water transport. Nutrient uptake from the soil occurs through active and passive transport processes. Understanding these transport mechanisms is crucial to understanding how plants efficiently distribute water and nutrients, ensuring their growth, development, and overall physiological processes.
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.
