Photosynthesis involves converting light energy into chemical energy. – Investigating Human Power. Method Set up a boiling tube containing 45 cm³ of sodium hydrogencarbonate solution (1%). This is an example of a common experiment used to investigate light intensity and the rate of photosynthesis. – Light Intensity Effecting Rate of Photosynthesis.
Investigating the rate of photosynthesis. A brief outline of various ways to measure the rate of photosynthesis - including measuring photosynthesis via the uptake of carbon dioxide (e.g.
The compensation point is the light intensity at which the rate of photosynthesis is equal to the rate of respiration.
The formula for photosynthesis is the following: 6C0 2 + 6H 2 O -- (light energy) --> C 6 H12O 6 + 6O 2 If we take a look at the different components of the equation, we can quickly determine a few ways of measuring the rate of photosynthesis. using immobilised algae), via the production of oxygen in pondweed, via the increase in dry mass, and via the production of carbohydrates. – Rate of Reaction Between Sodium Sulphate and Hydrochloric Acid.
– Height of Holly Leaves Affect Prickliness.
Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis. To investigate the effect of light intensity on the rate of photosynthesis. Investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pond weed. Green plants and algae use light energy to make glucose and oxygen from carbon dioxide and water. Practical - Investigation of factors affecting photosynthesis. – Using a light source, LDR and tracing paper to model absorption of gamma rays …
