Factors that affect rate of photosynthesis

The lights are also a source of heat which will affect the experiments with only a small distance between the light and the syringe. The simplest equation for photosynthesis: Although water is needed as a raw material for photosynthesis, if water is short, it will cause the plant to wilt and thereby lose its ability to capture sunlight long yester it limits photosynthesis at the biochemical level.

Water, Light and Temperature are the main one. At this concentration of CO2, energy is just sufficient to decompose it but not more.

As a result, C02 fixed by photosynthesis is lower than the C02 released by respiration. This test did produce a big anomaly. Photosynthesis is the conversion of light energy to chemical energy; the production of carbohydrates from carbon dioxide and water in the presence of chlorophyll by using light energy.

The line goes up steadily but then between a light intensity of and levels off very quickly. C3 plants become saturated Factors that affect rate of photosynthesis levels considerably lower than full sunlight but C4 plants are usually not saturated at full sunlight.

The elodea for this test was very close to the light source. They affect the dark reactions.

The factors that effect the rate of photosynthesis are: When other factors are not limiting, the rate of photosynthesis increases almost linearly with increase in light intensity. Plants need light in order for photosynthesis to take place.

On a deeper level, other factors like amount of chlorophyll, availability of nutrients e. Oxygen is inhibitory to photosynthesis because it would favour a more rapid respiratory rate utilizing common intermediates, thus reducing photosynthesis.

What factors affect photosynthesis?

When the intensity of light falling on a photosynthesizing organ is increased beyond a certain point, the cells of that organ become vulnerable to chlorophyll catalyzed photo-oxidations. Thereafter, it remains constant over a wide range of CO2 concentrations.

Carbon dioxide Carbon dioxide is the key inorganic molecule required for photosynthesis. At a point saturation may be reached, when further increase in light intensity fails to induce increase in photosynthesis.

The curve is very shallow and levels off towards a light intensity of - Besides chlorophyll certain protoplasmic factors also influence the rate of photosynthesis.

They need water to support the plant to face the sun as well as a raw material of photosynthesis. I suspect the rate of photosynthesis is limited by temperature today.

15 Main Factors Affecting Photosynthesis

Light is usually the limiting factor from dusk until dawn. When the light intensity is increased, then a higher concentration of CO2 will be decomposed and the rate of photosynthesis increases till light again becomes a limiting factor. Environmental pollutants dust, ash may clump onto the leaves and reduce the effectiveness of photosynthesis.

Photosynthesis also involves a series of enzyme-catalysed reactions. The rest of the tree, bark etc.

What are the Factors that affect Photosynthesis

What factors affect the rate of weathering? What factors influence the rate of photosynthesis? MERGE exists and is an alternate of. Water will not be a limiting factor as the plants are living in water. The main variables which affect photosynthesis are light, CO 2 concentration and temperature.

By using a different piece of elodea for each experiment did create the problem of it being impossible for each piece to have the same surface area. This pushed the air bubble in the capillary tube down. Light is usually the limiting factor from dusk until dawn. Light intenstity is a factor which can limit the rate of photosynthesis.

The action spectrum for photosynthesis in leaves shows two major peaks, one in the red and the other one in the blue Fig. Light intensity The intensity of light influences the rate of photosynthesis.Inwhen investigating the factors affecting the rate of photosynthesis, Blackmann formulated the Law of limiting factors.

This states that the rate of a physiological process will be limited by the factor which is in shortest supply.

Any change in the level of a limiting factor will affect the rate of reaction. The rate of photosynthesis increases with carbon dioxide concentration until the plant has enough or more carbon dioxide than it needs; at that point, the rate doesn't increase much further.

Temperature is also a major factor that affects photosynthesis, although this one works differently. The factors that effect the rate of photosynthesis are: the amount of sunlight, the amount of carbon dioxide, amount of water, intensity of. Many external and internal factors affect the rate 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. Light; Light is essential for photosynthesis.

The main variables which affect photosynthesis are light, water, CO 2 concentration and temperature. On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic.

The purpose of this experiment is to test whether factors such as light intensity and level of Carbon dioxide, will affect the rate of photosynthesis, which are the two most important variables in the photosynthesis process.
