Photosynthesis & limiting factors

What is the formula for Photosynthesis?

Carbon dioxide + water —chlorophyll+light —> glucose + oxygen

6CO₂ + 6H₂O ———> C₆H₁₂C₆ + 6O₂

What are the limiting factors for photosynthesis?

Termperature: if too little the enzymes won’t be at their optimum, if too much the enzymes will denature

Light intensity: If too light the rate of photosynthesis will be limited.

Carbon dioxide concentration: if too little the rate of photosynthesis will be limited.

Amount of chlorophyll: if too little the rate of photosynthesis will be limited as not much light can be absorbed.

What type of reaction is phosynthesis?

Endotheremic as it absorbs light

Why do farmers use the limiting factors to increase the rate of photosynthesis in greenhouses?

To increase the yield of crops.

How do farmers use the limiting factors to increase the rate of photosynthesis in greenhouses?

They increase the light, heat and add extra carbon dioxide to the greenhouses.

What is the problem with increasing the rate of photosynthesis in greenhouses?

It is expensive so the cost needs to be justified by the increase in yield.

What is a cost effective method farmers use to increase the rate of photosynthesis in greenhouses?

Oil burner as it heats and releases carbon dioxide at the same time.
