Explanation:
Answer:
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).
