Question

question 10 of 10 according to the graph below, at which point is the plant performing the least photosynthesis? oxygen in plants and time of day a. point d b. point a c. point b d. point c

Explanation:

Step1: Understand the relationship between photosynthesis and oxygen production

Photosynthesis produces oxygen. The lower the oxygen production rate, the less photosynthesis is occurring.

Step2: Analyze the graph

Looking at the "Oxygen Production Rate" on the y - axis, point A has the lowest oxygen production rate among points A, B, C, and D. Since oxygen is a product of photosynthesis, a lower oxygen production rate at point A indicates the plant is performing the least photosynthesis at that point.

Answer:

B. Point A
