Question

ASSESSMENT QUESTIONS:
WHICH OF THE FOLLOWING CAN BE USED TO MEASURE THE RATE OF PHOTOSYNTHESIS?
A. LIGHT INTENSITY (%)
B. OXYGEN PRODUCTION (ml/hr)
C. TEMPERATURE
D. CO2 LEVEL

Answer 1

All of the options provided can be used to measure different aspects that influence the rate of photosynthesis, but here are the most relevant ones:

A. **Light Intensity (%)** - Higher light intensity generally increases the rate of photosynthesis up to a certain point.

B. **Oxygen Production (ml/hr)** - This is a direct measure of photosynthesis, as oxygen is a byproduct of the process.

C. **Temperature** - Temperature affects enzyme activity and can influence the rate of photosynthesis.

D. **CO2 Level** - Carbon dioxide is a necessary substrate for photosynthesis, and increasing its concentration can enhance the rate of photosynthesis.

In summary, the best measures for the rate of photosynthesis specifically are **B (Oxygen Production)** and to some extent **A (Light Intensity)** and **D (CO2 Level)**. However, if you are looking for the most direct measurement of photosynthesis itself, **B (Oxygen Production)** would be the most suitable option.
