BIOMOLECULES AND ENZYMES

Detailed explanation-1: -•If the growth (or movement) of a plant part is away from the stimulus, then it is called negative tropism. • The movement of roots towards the pull of gravity is an example of positive geotropism, whereas the movement of plant stem in the direction opposite to the pull of gravity is an example of negative geotropism.

Detailed explanation-2: -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-3: -A tropism is plant movement in response to an external stimulus in the environment. If a plant moves towards a stimulus, then it exhibits positive tropism; if a plant moves away from a stimulus, then it exhibits negative tropism.

Detailed explanation-4: -Growth movement of plants towards the stimulus is known as positive tropism while movement of plant/plant parts away from the stimulus is known as negative tropism.

Detailed explanation-5: -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.
