PROJECT ( Biology ):- Oxygen is produced during photosynthesis in the presence of light.

TITLE:-  Oxygen is produced during photosynthesis in the presence of light.

AIM:-  To Show oxygen  is produced during photosynthesis in the presence of light.

MATERIAL REQUIRED:- 1. Beaker  2. Test tube 3. Water  4. Funnel  5. Hydrilla Plant.

PROCEDURE:-  Let us consider 1. Beaker  2. Test tube 3. Water  4. Funnel and  5. Hydrilla Plant as shown in figure below. 


*  place some water plant like hydrilla in a funnel and keep it in a beaker.
Then pour the water in the beaker.
*  Invert a test tube full of water over the stem of a funnel.
*  place on apparatus in the sun and the other in the dark for at least 2-3 hours. You would seed that in place       of water there is a air that fills in the set up kept in sun . It is actually a gas that will be collected in the test        tube.
*  observe the other set up kept in dark.
*  we found that difference in the amount of gas collected.

PRECAUTION:-  we all group members have done the experiment carefully.

RESULT:-  when we tested the gas in the test tube by interesting a glowing match stick or insence stick which would burst into flames. This shows the presence of oxygen.
