of environmental variables on the rate of photosynthesis.

□ BACKGROUND In the first part of the lab, students learn how to measure the rate of photosynthesis indirectly by using spinach from the produce section of the grocery story .photosynthesis lab.

It can also measure the rate of photosynthesis.

 [IMAGE] 1) Here as the light intensity increases so does the rate of photosynthesis.

DPIP is used to measure the rate of photosynthesis.

The spectrophotometer calculates the increase of light transmittance over time, therefore, calculating photosynthesis rate.
Dichlorophenolindophenol (DPIP) is used in this lab as an electron acceptor.

If the spinach leaves are not exposed to CO2, then they will not photosynthesize, because photosynthesis needs CO2 to work.

The photosynthesis equation is:
CO2 + H2O + Light C6H12O6 + O2
Photosynthesis is the process that a plant uses sunlight to synthesize food from CO2 and H2O.

In this experiment we were told that we would be measuring the rate of photosynthesis.

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .

Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.

The effect of light intensity on the rate of photosynthesis

I had
enough results to reach a conclusion and my results prove that light
intensity is effects the rate of photosynthesis: the further the light
the slower the rate of photosynthesis.

The effect of light intensity on the rate of photosynthesis ..

We compared our results with Anisha's group's results
and also I drew graphs of their group and this also clearly states
that the light intensity affects the rate of photosynthesis.

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.

Aim: To see if raising the light intensity increases the rate of photosynthesis.

Measuring the Rate of Photosynthesis

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

Prediction:I predict that raising the light intensity will increase the rate of photosynthesis.

rate of photosynthesis lab spinach

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.
