Question

Determining rate in white light. Calculate rate of volume change for Elodea in white light. Record in lab data

Answer 1

The rate of volume change can be used to find out how different lights (different wavelengths) affect photosynthesis and plant growth. To calculate it, we just need to record data of volume change and time.

------------------------------------------------------

To determine the rate of volume change, you need to use the following formula.

Rate of volume change (mL/hr) = Final volume  - Initial volume x 60

                                                                          Time

$\\ Rate of volume change (mL/hr) = ((Final volume - Initial volume)/ Time (min)) x 60 (min/hr)$

To calculate the rate of volume, we will use the following data.

If these values are different from yours, you just need to replace them acoording to the data in your table.

           Time (min)                                        White light volume                                    

                  0                                                             3

                  5                                                            4.3

                  10                                                          5.6

                  15                                                           6.9

                  20                                                          8.2                                                                                            

So, according to these values

• Final volume, Vf = 8.2 mL
• Initial volume, Vi = 3 mL
• Time, T = 20 min

Rate of volume (mL/hr) = ((Vf - Vi)/ T) 60

$\\ Rate of volume (mL/hr) = ((Vf - Vi)/ T) 60$

$\\ Rate of volume (mL/hr) = ((8.2 - 3)/ 20) 60$

$\\ Rate of volume (mL/hr) = 15.6 mL/hr$

The rate of volume change for Elodea in white light is 15.6 mL/hr.
