Tatiana [17]

Answer:

-1.9mL/min

Explanation:

The rate of O₂ production can be calculated by the formula

= ( Final volume - initial volume)/time(min).

From the graph provided and attached below, the rate of O₂ production or rate of photosynthesis at light intensity of 8 is about 3.75 mL/min.  

The rate of O₂ production is taken as the rate of photosynthesis. It is expected to progressively increase from light intensity 0 as light intensity increases. However, at very high light intensity, the rate slows down as water becomes limiting and the stomata closes in order to conserve water.

Question in order

Experiment 2: Respiration in the Dark

Calculate the volume change for respiration in the dark. As you already saw from earlier questions,

oxygen production is fairly constant. You will not need to calculate the individual volume changes.

Just subtract the original volume at 00:00:00 from the final reading at 00:02:00. Record your answer

for use in a later question.

<em>Note: depending on when you started the timer there is a range of possible answers. Pick the answer that is closest to this</em>
