Question

So I have 2 tables. The table with red numbers are the data to be use in order to find the values for the empty table.

So we need to find the data for the first table. It says here to calculate the values: (values for each time interval) - (reading at T=0)

I dont know what to do next or where to start.

2. a. Using the class data (Table 1) for your lab section complete Table 2 by calculating the corrected change in carbon dioxide and oxygen gas over time. The formula is provided below. Table 2: Production of carbon dioxide or oxygen gas by a spinach leaf under different light regimes. (12 marks) Light Time (minutes) Intensity LE/m/s T=0 T=2 T=4 T=6 T8 T510 T=12T=14 Dark (CO2) Dark (02) 0 50 pE/m/s (02) 75 pE/m²/s (02) 100 pE/m/s 0 (02) 225 pE/mº/s 0 (02) *To calculate the above values: (Value for each time interval) - (Reading at To) left-oxygen ridt-02 b. (14 marks) Graph the data in Table 2. Use two y-axi, the left one representing the change in oxygen gas over fime and the right one representing the change in carbon dioxide gas over time. Include a legend and a descriptive caption. ** Append the graph to your assignment * [CO2] 1 ppm Time lind

Answer 1

Light Intensity (in µE/m2/s )			Time (minutes)
	0	2	4	6	8	10	12	14	16
Dark (CO2)	0	92	179	249	330	402	462	508	549
Dark(O2)	0	140	5	-379	-553	-841	-1247	-1668	-2084
50 µE/m2/s (O2)	0	271	398	222	-96	-155	-367	-505	-372
75 µE/m2/s (O2)	0	-62	-409	-686	-892	-1174	-1112	-1380	-1310
100 µE/m2/s (O2)	0	-208	-476	-685	-547	-539	-526	-330	-124
225 µE/m2/s (O2)	0	130	224	575	1048	1631	2163	2893	3351

The above table has been created using the given formula.

I m providing the graphs as two versions of the above data:-

Graph 1 and 2 are separate graphs for CO2 and O2 which is as follows:-

Graph 1

4000 3000 2000 1000 Light INtensity Dark(02) 50 pE/m2/s (02) -75 pE/m2/s (02) - 100 pE/m2/s (02) 225 pE/m2/s (02) 0 2 4 6 8 10 12 14 16 -1000 — -2000 -3000 Time(min)

Graph 2

Dark (CO2) Light Intensity — Dark (CO2) O+AT 0 2 4 6 12 14 16 8 10 Time (min)

Graph 3 is a combined graph for O2 and CO2:-

4000 3000 2000 100d Light Intensity Dark (CO2) Dark(02) 50 pE/m2/s (02) —75 E/m2/s (02) — 100 E/m2/s (02) — 225 pE/m2/s (02) 0 2 4 6 8 10 12 14 16 -1000 -2000 -3000 Time (min)
