What is the chemical reaction of photosynthesis?

What is the chemical reaction of photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

How does light affect photosynthesis?

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. At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.

Which light is the best for photosynthesis?

The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

What color light helps photosynthesis?

green light

Why does light increase the rate of photosynthesis?

Light intensity – Increasing light intensity increases the rate of photosynthesis because more energy is provided. However, if the light intensity is increased above a certain threshold, the rate of photosynthesis will not increase because another factor (such as temperature) is limiting the rate of the reaction.

Which factor will increase the rate of photosynthesis?

Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply.

What light intensity will maximize the rate of photosynthesis?

The highest light intensity and CO2 level will maximize the rate of photosynthesis. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold? If the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use.

What name is given to a factor which is preventing an increase in photosynthesis?

A limiting factor is simply anything in short supply that prevents photosynthesis occurring at its maximum rate. If photosynthesis occurs more slowly in plant cells then a lower quantity of sugar will be produced and the quantity of chemical energy available for cell growth will be reduced.

What are the external factors affecting photosynthesis?

External Factors Affecting Photosynthesis

• Carbon dioxide. In C3 plants, the rate of photosynthesis increases with an increase. In CO2 concentration upto 500 ml.
• Irradiance or Light Intensity. Both quality and intensity of light influence the rate of photosynthesis.
• Temperature.

What are the internal and external factors of photosynthesis?

The external or environmental factors at:A light intensity, carbon dioxide concentration and temperature. The internal factor influencing the photosynthesis is chlorophyll content of the leaves and protoplasmic factors.

What are the internal and external factors that affect the rate of photosynthesis?

A limiting factor is a factor which is deficient to such an extent that an increase in its value directly increases the rate of the process. Some of the external factors which affect the rate of photosynthesis include carbon dioxide, light, temperature, water and DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea).

What are the steps of respiration in plants?

Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.

How many types of respiration are there in plants?

two types

What is the importance of respiration in plants and human?

The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
