FACTORS AFFECTING PHOTOSYNTHESIS

Here In This Article, we are going to List out Factors affecting Photosynthesis and we are going to explain them.

Below are the Factors that Affect Photosynthesis:

LIST OF FACTORS AFFECTING PHOTOSYNTHESIS

  1. LIGHT INTENSITY
  2. CARBON ( IV ) OXIDES
  3. WATER
  4. TEMPERATURE
  5. CHLOROPHYLL CONCENTRATION
  6. HIGH CONSCONCERNTRATION  OF OXYGEN
  7. INHIBITORS
  8. POLLUTION

Factors Affecting Photosynthesis

LIGHT INTENSITY

Light is necessary for Photosynthesis to take place . The rate of Photosynthesis increases with moderately high light Intensity while the rate is decrease with low light intensity.

Very high light intensity reduces the rates of Photosynthesis as chlorophyll is being bleached and enzymes denature.

CARBON ( IV ) OXIDES

Carbon ( IV ) Oxides is also necessary raw materials in photosynthesis.  The more Carbon ( IV ) Oxides In  the photosynthetic cells the faster the rate of photosynthesis.

WATER

Water is an essential raw material for photosynthesis.

TEMPERATURE

The light and dark reactions are controlled by enzymes.  The low or high temperatures will negatively affect enzymes action, hence a decrease in the rate of photosynthesis.

CHLOROPHYLL CONCENTRATION

The reduction of chlorophyll level decreases the rate of photosynthesis. High light Intensity, mineral deficiency diseases, and aging processes reduce chlorophyll concentration.

HIGH CONSCONCERNTRATION  OF OXYGEN

A high concentration of oxygen in the atmosphere decreases the rate of photosynthesis.

It has been shown that oxygen competes with Carbon ( IV ) Oxides for an active site in the Carbon ( IV ) fixing enzyme ( carboxylase ), thus reducing the amount of Carbon ( IV ) Oxides, thereby decreasing the rate of photosynthesis.

INHIBITORS

Herbicides such as DCMU ( Dichlorophenyl dimethyl urea} inhibits the electron flow of the chloroplasts thereby decreasing the rate of photosynthesis.

POLLUTION

Gases and materials of industrial waste discharged into the atmosphere also affect the rate of photosynthesis.

Sulphur ( IV } Oxides and ozones for example, damages the leaves of plants.  Soot and dust particles block the stomata slowing down the rate of exchange of gases thus decreasing the photosynthesis rate.

Soot and dusts also reduce the intensity of sunlight, hence photosynthesis rate is reduced.
