How does the process of phototropism demonstrate control and coordination in plants?
1
By regulating water absorption
2
By responding to light stimuli
3
By controlling temperature
4
By producing oxygen
Answer and Solution
Answer
B. By responding to light stimuli
Solution:
Phototropism is a plant's growth response towards light, allowing it to optimize light absorption for photosynthesis. This process demonstrates control and coordination in plants by enabling them to adjust their growth direction based on the location of a light source. Phototropism helps plants maximize their exposure to sunlight for energy production. Therefore, the correct answer is 'By responding to light stimuli'.
