Question

enlisted the basic requirements of photosynthesis​

Answer 1

Basic requirements for photosynthesis to occur in plants;

• proper amount of CO2 in the air

• H2O from the roots from the earth beneath it.

• Sunlight for energy

• Suitable temperature

• Suitable intensity level of the sunlight

Answer 2

Answer:   Water, sunlight, carbon -dioxide, temperature are the basic requirement of photosynthesis.

Explanation :

WATER:

• Water is one of the reactants in light reaction.
• The effect of water as a factor is more though its effect on plant rather than directly on photosynthesis.
• Water stress causes the stomata to close hence reducing the CO2 availability.

• Its reduces the surface area of the leaves.

SUNLIGHT :

• It increase in incident light beyond a point causes the breakdown of chlorophyll and a decrease in photosynthesis.
• The linear relationship between incident light and co2 fixation rate at low light intensities.

CARBON - DIOXIDE:

• It is the main limiting factor of photosynthesis.
• The C3 and C4 plants respond differently to CO2 concentrations.
• They allowed to grow in carbon dioxide enriched atmosphere that leads to higher yields.

TEMPERATURE:

• The dark reaction being enzymatic are temperature controlled.
• the light reactions are also temperature sensitive they are affected to a much longer extent.
• The temperature optimum for photosynthesis of different plants depends on the habitat that they are adopted to.
