Plant Growth and Development
Plant growth and development is studied to understand the complex processes that regulate the life cycle of plants. It helps us to understand various components of a plant’s body, like meristematic tissues (the tissues containing actively dividing cells) that contribute to primary and secondary growth. Plant hormones (such as Auxins, Gibberellins, Abscisic acid, Ethylene, and Cytokinins), that play an important role in regulating growth patterns, Phototropism, fruit maturation, abscission of leaves, and tropic responses. The cell cycle helps in understanding the fundamentals of plant physiology, which ensures the formation of new cells for growth. Additionally, the differentiation of cells into various tissues and organs contributes to the overall structure of the plant. The concept of photoperiodism, responding to day length, influences flowering and reproduction. A detailed understanding of these biological processes provides us with knowledge of the complex mechanisms governing plant growth, development, and adaptation to environmental changes.
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.
