State 2 different types of movement in plant
Answers
Different moment is plants are
- Geotropism
- Chemotropism
- phototropism
- Thermotropism
- Hydrotropism
- Thigmotropism
Answer:
Let us see different types of tropic movements in plants and how plants control and coordinate in brief.
Tropic movements
When a plant shows some growth movement in response to a stimulus, it is known as tropism. Tropism is a direction, which is specific and depends on the direction of the stimulus. Plants may either show a positive or negative movement as a response to a stimulus. If the movement is towards the direction of stimuli, it is known as positive tropism, if the movement is away from the stimuli, it is known as negative tropism. Discussed below are a few types of tropism.
Phototropism: Plants grow towards or away from the light, the type of tropism in the response to light is called phototropism. In general, the stems usually show positive phototropism, while roots show negative phototropism. Leaves also positively respond toward the source of light.
Gravitropism: It is a type of tropism where plants show some growth in response to the gravity. Stems are negative to the gravitropism while roots are positive to the gravitropic. This is also referred to as geotropism. Among different parts of plants, the primary roots and certain other portions of the root system show positively geotropic by growing directly towards the center of gravity. The stems are called as the negatively geotropic as they grow away from the center of gravity. The leaves are transversely geotropic as they select their positions at right angles to the center of gravity.
