Question

2 of 4 Effect of Light Intensity Level on Photosynthesis a First set the tomp set at 25 degrees Celsius: Set the lamp so that the light is he the levels found in the data table, count and record the number of bubbles generated by the elodea at each light setting for 1 minute. You will need to time this yourself as the below and answer ail questions in the question and answer format Fil out each table below. Each table is worth 10 points Temperabure 25 degrees Celsius (77 degrees Fahrenheit) Light Levels e Number #1 | #2 20 30 1. The sate of photosynthesis is moasured by the frequency of butibies generated by the water plant (Elodea) in the cylinder of water. What gas is being generated by the plant? ( 5 points) 2 Based on the dala that you just collected what happens to the rate of photosynthesis as the light intensity increases? That is, how does the ight intensity aflect the rate of photosynthesis? (5 points) Now increase the temperature from 25 to 40 degrees Celsius and repeat the experiment Celsius (104 degrees Fahrenheit) Tnal Trial Average Number #1 |#2 Light Levels 10 20 30 50 3. How does the increase in temperature affect the rete of photosynthesis? (5 points) 4 What are the variables in this experiment? (5 points)

Explanation / Answer

Ans-1 during photosynthesis the plants which are submerged in to water makes bubble of gas as the gases pass in and out of the stomata. This gas released from the tiny spaces surrounding the stomata is responsible for the production of bubbles. The gas which is generated is oxygen.
