What is Plant Physiology? – Meaning & Definition
Definition of Plant Physiology:
Plant Physiology is the branch of botany that deals with the study of the functions and processes occurring in plants. It explains how plants grow, develop, and respond to their environment at the cellular and biochemical levels.
Meaning of Plant Physiology:
Plant Physiology focuses on the internal functions of plants, such as photosynthesis, respiration, nutrient absorption, water transport, and hormone regulation. It helps us understand how plants survive, adapt, and reproduce under different conditions.
Key Areas of Plant Physiology
Photosynthesis – How plants produce food using sunlight.
Respiration – How plants break down food to release energy.
Water & Nutrient Transport – Movement of water and minerals through xylem & phloem.
Plant Hormones – Regulation of growth, flowering, and responses to stimuli.
Seed Germination – Process by which a seed develops into a plant.
Plant Movements – Tropisms (response to light, gravity, and touch).
Importance of Plant Physiology
Helps in crop improvement & agriculture
Enhances plant growth & productivity
Aids in understanding plant responses to climate change
Supports medicine & biotechnology research

What is Plant Physiology?
Definition:
Plant Physiology is a branch of botany that deals with the study of the functions and processes occurring in plants.
It focuses on how plants live, grow, and respond to their environment at the cellular, tissue, and whole-plant level.
Meaning (in simple terms):
Plant Physiology is the science that explains how plants work — how they:
-
Make food (photosynthesis)
-
Use water (transpiration)
-
Grow and move
-
Respond to light, gravity, and chemicals
Key Areas of Plant Physiology:
| Function | Description |
|---|---|
| Photosynthesis | How plants make food using sunlight |
| Respiration | Energy release from food in plant cells |
| Transpiration | Loss of water through leaves |
| Mineral Nutrition | Absorption and use of minerals from the soil |
| Plant Growth & Hormones | Study of auxins, gibberellins, cytokinins etc. |
| Photoperiodism & Tropism | Plant response to light, gravity, touch, etc. |
