Question

explain the process of photosynthesis in plants. list four factors which influence this process and describe how each of them affects the rate of photosynthesis process

Answer 1

The term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place. This can be measured by the amount of glucose produced by a plant over a given time. This topic is especially important to scientist and farmers. By understanding the factors that affect the rate of photosynthesis they can do work to try and increase the rate of photosynthesis to increase the yield of a crop.

The three main things affecting the rate of photosynthesis are:

Light

Temperature

Carbon dioxide

These three factors are called LIMITING FACTORS.

 

In a process like photosynthesis which is affected by more than one factor, its rate is limited by the factor which is closest to its minimum value. So at any point in time if one of the three factors is in low supply, this factor will be the limiting factor. Only a change to the limiting factor will increase or decrease the rate of photosynthesis. Changing the other two will have no effect.

Answer 2

HEY MATE!!

■ Absorption of light energy by chlorophyll.

■ Conversion of light energy to chemical energy.

■ Splitting of water molecules.

■ Reduction of carbon dioxide to carbohydrates.
