Question

multiple choice 2 points
oxygen production during photosynthesis throughout the day
based on the photosynthesis equation and the pattern shown in the graph, which statement is correct?
oxygen is a product of photosynthesis, so its produced during daylight
oxygen is produced at a constant rate throughout the 24 - hour period
oxygen production is highest at night when plants are resting
oxygen is a reactant in photosynthesis, so its consumed during daylight

Explanation:

• The photosynthesis equation is \(6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2\). So, oxygen (\(O_2\)) is a product of photosynthesis.

• Looking at the graph, oxygen production rate is non - zero during daylight hours (approx 6 - 18 hours) and zero at night.

Answer:

Oxygen is a product of photosynthesis, so it's produced during daylight.
