About This Book
Plant physiology is the branch of botany that focuses on the functions and processes that occur within
plants. It encompasses a wide range of topics, including the way plants grow, develop, and interact with
their environment. Understanding plant physiology is crucial for improving agricultural productivity,
managing plant diseases, and conserving plant species. One of the core processes in plant physiology is
photosynthesis, the process by which plants convert light energy into chemical energy stored in glucose.
This occurs in the chloroplasts of plant cells, primarily in the leaves. Photosynthesis is essential for plant
growth as it provides the energy required for other metabolic processes. Another important aspect is
water transport in plants. Plants absorb water through their roots and transport it to the leaves via the
xylem. This process involves the movement of water due to transpiration, where water evaporates from
the leaves, creating a pull that helps to draw water upwards. This is crucial for nutrient transport and
maintaining cell turgidity. Plant growth is regulated by hormones such as auxins, gibberellins, and
cytokinins. These hormones influence processes like cell division, elongation, and differentiation.
Additionally, plant physiology includes the study of nutrient uptake, respiration, and the impact of
environmental factors like light, temperature, and soil composition on plant health. Understanding
these processes helps in optimizing agricultural practices and enhancing plant growth. Basics of Plant
Physiology offers a comprehensive introduction to the key processes and functions that govern plant life,
including photosynthesis, water transport, growth, and response to environmental stimuli.
