Question

A gas is released during photosynthesis.State the way in which gas is evolved

Answer 1

carbon dioxide is taken and oxygen is released

Answer 2

During this process of sugar production, carbon dioxide combines with water to  form glucose and oxygen is released.  Oxygen that is produced in photosynthesis  is given off as a gas.  If a lot of oxygen is being given off, photosynthesis is occurring rapidly.  If little oxygen is being given off, photosynthesis is   occurring slowly.  The amount of trapped light energy and the amount of carbon  dioxide available affects the rate of photosynthesis.
