Question
If the distance of a desk lamp from a water plant, elodea, is increased you would expect the rate of photosynthesis...A:To stay the sameB:To rise due the the intensity of light fallingC:To rise due to the intensity of light risingD:To fall due to the intensity of light falling
Solution
The correct answer is D: To fall due to the intensity of light falling.
Here's why:
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. In this process, light energy is converted into chemical energy.
The intensity of light is a crucial factor for photosynthesis. The closer the light source is to the plant, the more intense the light is, and thus the rate of photosynthesis is higher. Conversely, if the light source (in this case, the desk lamp) is moved further away from the plant, the intensity of the light falling on the plant decreases. This decrease in light intensity reduces the rate of photosynthesis.
So, if the distance of a desk lamp from a water plant, elodea, is increased, the intensity of light falling on the plant decreases, and as a result, the rate of photosynthesis falls.
