Chemical Coordination in Plants – Notes
Control and Coordination – Coordination in Plants
Plants show two different types of movement- One independent of growth and the other dependent on growth.
Plants growth in the direction of stimulus is defined as tropic movement.
The movement of a plant part is response to light is called phototropism.
The movement of a plant part is response to gravity is called geotropism.
The movement of a plant part is response to chemicals is called chemotropism.
The movement of a plant part is response to water is called hydrotropism.
The directional growth movement of a plant part in response to the touch of an object is called thigmotropism.
Plants have different hormones which help coordinate growth development and response to the environment.
