The rate of photosynthesis depends, of course, on how much carbon dioxide is present in the atmosphere. This dependence varies from species to species. For example, in tobacco, the net rate hits zero (photosynthesis consumption of CO2 equals repiration release of CO2) at .05 ppt carbon dioxide; maize (which has a different biochemistry of the ...

Net photosynthesis must be positive for growth to occur. Negative net photosynthesis (due to shading, water stress, or old leaves) will cause death by starvation. Net photosynthesis per square meter (m2) Net photosynthesis per plant multiplied by the number of plants per square meter. Net photosynthesis per plant A measurement equal to ...

The length of time it takes for leaf disks to float again is a measure of the net rate of photosynthesis. This process is shown in Figure 3. Procedure: In this part of the lab, you will learn how the floating leaf disk technique can measure the rate of photosynthesis by testing a …

The process of photosynthesis can be expressed by the following word equation and chemical equation. Carbon dioxide + Water ( Glucose + Oxygen. 6 CO2 + 6 H2O ( C6H12O6 + 6 O2. In this lab, you will be using leaf disks, to assay the net rate of photosynthesis under various lighting conditions.

2.Use your recorded data to find the rate of change in DO concentration when the light is shining on the plant and the rate of change in DO concentration when the plant is in darkness. Use 2 methods: 1) the slope of a linear fit line and 2) the 2-point method. Show your work.

It is a rate, the quantity of new vegetable matter added per day, per week or per year. Net primary productivity is calculated as the total gain of biomass from photosynthesis minus the losses due to plant respiration. It is this net gain that is available to other organisms as food.

9. Add the net change during photosynthesis to the net change during aerobic cellular respiration. Record the sum as Gross Change – Photosynthesis (Green Light). 10. Calculate the Rate of Photosynthesis –Green Light (per hour) by multiplying Gross Change – Photosynthesis (Green Light) by 6. Record your results in the Lab Report section.
