1. In the Mimosa pudica plant, when we touch the leaves of the plant they fold up. Here the stimulus is touch.
2. In a dandelion flower, the opening up of the petals of this flower in the morning in bright light and closing in the evening when light fades. Here, the stimulus is light.
We can say that Nastic movement may or may not be a growth movement because we have seen above that folding up of the leaves of a sensitive plant on touching is not a growth movement but the opening and closing of petals of flowers is a growth movement.

The non-directional movement of a plant in response to the contact of an object is called Thigmonasty movement. In the insectivorous plant’s leaves like Drosera, Dionaea the tentacles show variation in movements on coming in contact with an insect. The stimulus touch of an insect is transmitted to the entire leaf and all the tentacles bend over the insect.

Phototropism: This directional movement occurs in response to light.

Geotropism. It is a type of tropism where plants show some growth in response to gravity. ...

Chemotropism. There are few chemical substances, which are actively responsible for bringing a curvature movement in plant organs. ... example: movement of pollen tube towards ovary

Hydrotropism: Movement of roots to the source where water content is higher.

Thigmotropism: Movement of plant parts towards a support like movement of tendrils of climbers

The non-directional movement of a plant part usually in the petals of flowers in response to light is photonasty movement. The stimulus in Photonasty is light. Many petals of flowers open in the daylight and closed in the evening in response to the intensity of light. This is a growth movement in plants and an example of Photonastic movement. Examples are: Dandelion flower, Moonflower, flower of Cestrum Nocturnum etc.

This movement is caused due to the variations in light and temperature. It is also known as Sleeping movement. It can be classified under Photonastic and Thermonastic movement. It is seen in leguminous plants. The leaflets fold in the evening and open up in the morning.

Q1. Design an experimment to show hydrotropic movement.
Q2. Describe the type of movement shown by sunflower and touch me not plant

Such movements in plants occur due to the change in temperature. Flowers of a plant open with the rise in temperature and close with a drop in temperature. Sometimes Thermonastic movement is associated with Photonastic movements also. In these both, the response mechanism is related to the growth, changes in the turgor on upper and lower sides of the petiole, leaf blade etc.
