How do environmental signals like light and gravity influence plant growth?
Understand the Problem
The question explores the influence of environmental factors such as light and gravity on plant development. It seeks to identify the correct way in which these external cues impact plant growth stages.
Answer
Light and gravity influence plant growth through tropisms, such as phototropism (response to light) and gravitropism (response to gravity), which involve hormonal signals and cell growth.
Environmental cues like light and gravity influence plant growth through tropisms. Plants use gravitropism to orient themselves in the soil before light is available. Once seedlings emerge, phototropism directs their growth toward light. These tropisms involve hormonal signals that affect cell growth, leading to movement and orientation.

Environmental cues like light and gravity influence plant growth through tropisms. Plants use gravitropism to orient themselves in the soil before light is available. Once seedlings emerge, phototropism directs their growth toward light. These tropisms involve hormonal signals that affect cell growth, leading to movement and orientation.
More Information
Plants exhibit tropisms, which are growth responses to environmental stimuli. These responses are crucial for survival, as they enable plants to orient themselves effectively for light capture and root establishment.
Tips
A common error is thinking that plants only respond to one stimulus at a time. In reality, plants integrate multiple signals to optimize their growth strategy.
