Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following would most affect the rate of photosynthesis?
A
Amount of carbon dioxide in the atmosphere
B
amount of water in the soil
C
amount of sunlight
D
All of the above
Explanation: 

Detailed explanation-1: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Detailed explanation-2: -As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Detailed explanation-3: -The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.

Detailed explanation-4: -Three factors that affect the rate of photosynthesis are temperature, light intensity, and the availability of water.
