What is plant physiology? Scope of plant physiology

Definition of Plant physiology

Plant physiology is the study of the internal function of plants. It is a sub-discipline of botany. Plant physiology is related to plant morphology, plant ecology, photochemistry, and cell biology.

The fundamental process of plants physiology includes:





Seed germination


Plant water relation


Circadian rhyme

Nastic movement


Environmental stress

Dormancy and stomata function


Scope of plant physiology.

The field of plant physiology includes the study of all internal functions of plants, chemically and biologically.

Plant physiology has 5 Scopes, These are:

1. The study of plant physiology includes the study of how plants produce a chemical in order to manufacture food and depend on themselves.

plant physiology

Plants produce chemicals that are not available in other organisms. They use some of those chemicals to attract pollination, plants use other chemicals to depend on themselves from herbivores by producing smelling chemicals, those chemicals also prevent them from diseases.

2. The study of plant physiology includes the study of the biological and chemical processes of the plant cells. A plant cell has features that differ from an animal cell. For example, a plant cell has a cell wall that limits flexibility. It also has chlorophyll that interacts with light to enable plants to manufacture their own food instead of depending on other organisms like how animals do.

3. Plant physiology includes the study of the interaction between cells, tissues, and organs within the plant. Different cells, tissues, and organs are specialized physically or chemically to perform different functions. For Example, Roots, and rhizoids fixed the plant, leaves catch light which is used by the plant to manufacture their own food.

4. Plant physiology includes the study of how plants regulate their internal functions. Plants produce hormones that are used to signal the cell to other parts of the plant.

5. Plant physiology also includes the study of how plants respond to conditions in the environment.
