how do plants exhibit movement and respond to stimuli
Answers
Answer:
Phototropism – It is the movement of plants in response to light. The shoot system of a plant exhibits this characteristic. The shoot moves towards the light. ... Chemotropism – It is the movement of plants in response to a chemical stimulus.
Answer:
please mention the subject correctly
u had written maths
anyway I know the answer
answer is
Coordination is the ability to use different parts of the plant together, smoothly and efficiently. In plants, coordination is due to the result of a chemical system, wherein plant hormones or phytohormones have a major role.
Movement in plants
Plants exhibit two types of movements.
Growth-dependent movements called the Tropic Movements. ( towards or away from a stimulus)
Non-growth dependent movements called the Nastic Movements. ( independent of stimulus)
Tropic movements
These can be classified again into 5 types. They are:
Phototropism (light)
Geotropism (gravity)
Hydrotropism (water )
Chemotropism (chemicals)
Thigmotropism (touch)
Phototropism – It is the movement of plants in response to light. The shoot system of a plant exhibits this characteristic. The shoot moves towards the light.
Geotropism – It is the movement of a plant part towards the soil. This is a characteristic of the root system. The roots always move in the direction of the earth’s gravity.
Hydrotropism– It is the movement of a plant towards the water. The stimulus here is water.
Chemotropism – It is the movement of plants in response to a chemical stimulus. A classic example of this type of movement is the growth of the pollen tube towards the ovule, during fertilization, in a flower.
Thigmotropism – It is a directional movement in plants in response to touch. For e.g. the plant tendrils climb around any support which they touch.
