You will also look at cells from a leaf of the plant Elodea. The cells of this plant are green because they contain the pigment, chlorophyll. This is a pigment found in chloroplasts and allows a plant to absorb sunlight and manufacture its own food. Materials: Microscope. Slides. Cover slips. Toothpick. Pipette. Elodea. Forceps. Lugol’s ...
Effect of Temperature on the Rate of Photosynthesis
The Plant Cell. Introduction. ... Life: Unless you kill them with rough handling, slides of onion epidermis and the Elodea leaf will show living cells. Most staining procedures for the light microscope and all preparation of material for the transmission electron microscope, however, result in the death of the cells. ... Allow transfer ...

Photosynthesis in Elodea. In an intact plant, both electron transport and carbon fixation will continue as long as the plant is illuminated, and it is possible to study the effect of light intensity and the concentration of CO2 on the rate of photosynthesis.

Position Lamp 10cm from Elodea with beaker of water in between lamp and Elodea and switch lamp on. Start stop clock and measure 2 minutes. After 2 minutes pull Elodea from capillary tube and use the gas syringe to pull the air bubble up the capillary tube so that the end is at 0mm on the scale. Measure the length of the air bubble produced.
