Detailed explanation-1: -Tropism is when a plant moves in response to an external stimulus in the environment. Positive tropism is when a plant moves towards a stimulus. Negative tropism is when a plant moves away from a stimulus.

Detailed explanation-2: -A tropism is a growth response a plant undergoes when it is stimulated by an environmental factor. Environmental factors, including light, chemical nutrients, water, and gravity are stimuli that can provoke tropisms in a plant.

Detailed explanation-3: -tropism, response or orientation of a plant or certain lower animals to a stimulus that acts with greater intensity from one direction than another. It may be achieved by active movement or by structural alteration.

Detailed explanation-4: -In biology, phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs.

Detailed explanation-5: -Chemotropism-Chemo-tropism is the growth of plants, navigated by chemical stimulus from outside of the organism or organisms part. The response of the organism or organism part is termed positive if the growth is towards the stimulus or negative if the growth is away from the stimulus. Was this answer helpful?
