Elodea essay

Light Colour Length grown cm Blue 1. How ever the green light photosynthetic rate was lower than the red light photosynthetic rate. We added four to five drops of the phenol red to the test tube.

We set aside the paper to let it dry. I thought that the water in the container that had plant with the highest photosynthetic rate would become acidic because more carbon dioxide is produced by the plant in respiration. But right before smearing them, we observed them and described what we saw.

Waterfowl, especially ducks, as well as beaver and muskrat eat this plant. The test tubes that contain the laundry detergent- gelatin mix will stay runny because of its water-like composition. Elodea often overwinters as an evergreen plant in mild climates like New Zealand.

After a day, the water was yellow, proving the hypothesis. This is because these colours contain more energy, for according to the colour spectrum, they are of shorter wavelengths, and the shorter the wavelength, the more energy is present.

I got the same ph 8 for all the containers. Here are my averaged data results. Test tube 8 was also a control, and was placed in the dark. It was only due to time, not distance. Test tube 2 was placed in the dark.

Light wavelength effect on the photosynthetic rate of elodea Essay Sample

I got the same ph 8 for all the containers. This is because the plant was in the test tube by itself, and placed in the light so the elodea could freely photosynthesize, which would eliminate a large portion of the carbon dioxide within the tube.

I repeated the experiment, but this time I decided to remove the watt lamp and instead of measuring the ph of water measure the number of bubbles on each plant everyday and on the fifth day the elodea segments were removed from the container, measured and recorded again to see the amount grown in length during the five-day period.
