Vegetal movements respond to the action of hormones or environmental factors such as chemicals, sunlight, or mechanical shocks.
These movements can be growth and curvature and locomotion type.
Growth and Curvature Movements
These movements can be of the type tropisms and nastisms.
Tropisms are movements oriented in relation to the stimulus source. They are related to the action of auxins.
Phototropism It is movement oriented by the direction of light. There is a curvature of the plant in relation to the light, which may be towards or against it, depending on the plant organ and auxin hormone concentration. The stem has a positive phototropism, while the root has a negative phototropism.
Geotropism It is the movement guided by the force of gravity. The stem responds with negative geotropism and the root with positive geotropism, depending on the auxin concentration in these organs.
Chemotropism It is the chemical-oriented movement of the environment.
Tigmotropism It is the movement guided by a mechanical shock or mechanical support, as with the chayote and passion fruit tendrils that coil when they come in contact with any mechanical support.
