Answer:-Gravitropism. 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. ...
Thigmotropism. ...
Hydrotropism. ...
Thermotropism. The below mentioned article will highlight the six types of tropic movements in plants.
The six types are: (1) Thigmotropism (Haptotropism) (2) Phototropism (3) Geotropism (4) Thermotropism (5) Chemotropism and (6) Hydrotropism. A tropism is a growth movement whose direction is determined by the direction from which the stimulus strikes the plant. There are two forms: Positive = the plant, or a part of it, grows in the direction from which the stimulus originates. and Negative = growth away from the stimulus. tropism is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the stimulus (as opposed to nastic movements which are non-directional responses).
