Light intensity, carbon dioxide levels, temperature.
Problem: To what extent does distance from a light source (5cm, 10cm, 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min.) in Elodea water plants.
Elodea Lab Background: Today you will be working with the aquatic plant, elodea, also known as anacharis.
Hypothesis According to the concept of photosynthesis, elodea could.
The oxygen production will only be abundant if the light is normal, or red or blue wavelengths.
The Photosynthesis rate can be observed by measuring the rate of decrease in carbon dioxide concentration.
Photosynthesis Experiment in Elodea in Direct ..
A further question for research is, what is the amount of sodium bicarbonate that will not increase the speed of photosynthesis anymore, and the speed of rising punches will reach a plateau?
Rate of Photosynthesis in Elodea ernstiae ..
In this procedure, algae, immobilised in calcium alginate, provide a standardised amount of photosynthetic material, enabling semi-quantitative experiments to be undertaken. The rate of carbon dioxide uptake by the immobilised cells is used to measure the rate of photosynthesis; this can be done simply by observing the colour change of hydrogencarbonate indicator, either by eye or using a colorimeter.

Light colour: Certain colours of light can change the rate of
photosynthesis in green plants such as elodea depending on how well
the light can be absorbed into the plants chlorophyll.
