Which of the following statements accurately describes the difference between the two types of plant movement discussed in the text?
Understand the Problem
The question is asking for an accurate description that differentiates between two types of plant movement mentioned in a text. Each option presents a different statement about these movements, and the task is to identify which one is correct based on their characteristics.
Answer
Tropism is direction-dependent growth; nastic movement is non-directional.
Tropism involves directional movement in response to stimuli, such as light or gravity, leading to growth towards or away from the stimulus. This distinguishes it from nastic movements, which do not depend on the direction of the stimulus and occur in response to stimuli like temperature and touch.
Answer for screen readers
Tropism involves directional movement in response to stimuli, such as light or gravity, leading to growth towards or away from the stimulus. This distinguishes it from nastic movements, which do not depend on the direction of the stimulus and occur in response to stimuli like temperature and touch.
More Information
Tropisms require slow growth changes in the plant's structure, whereas nastic movements are usually quicker and result from changes in water pressure within plant cells.
Tips
A common mistake is confusing tropism with nastic movements, which are not related to the direction of the stimulus.
