BBC - GCSE Bitesize: Factors limiting photosynthesis

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...

In practice, any one of these factors could limit the rate of photosynthesis.

Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (singular: stoma. plural: stomata)

The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf. This also allows the oxygen produced in photosynthesis to leave the leaf easily.




Carbon dioxide is present in the air we breathe, at very low concentrations. Even though it forms about .04% of the air, it is a needed factor in light-independent photosynthesis.

In higher concentrations, more carbon is incorporated into carbohydrate, therefore increasing the rate of photosynthesis in light-independent reactions.

I think this because light is the most important thing needed for photosynthesis.

Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis.

Photosynthesis, process by which green plants and certain other organisms. important byproduct of photosynthesis is oxygen, on which most organisms depend. The pigments and enzymes are arranged in two types of units, Photosystem I. Photosynthesis is the process by which plants and algae feed. Homepage / biology / The 3 Stages of the Most Important Photosynthesis. Chlorophyll is a pigment that is present in the tissues of green plants; Usually. The process of photosynthesis occurs when green plants use the energy of. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the. An extremely important by-product of photosynthesis is oxygen, on which most organisms.

Factors Affecting Rate of Photosynthesis

Plan ==== The factors affecting photosynthesis are: Light - This will affect photosynthesis because it is one of the limiting factors.

Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.


Therefore light is a limiting factor because the rate of
photosynthesis can increase if the intensity of light is strong, but
only to a point, after that the rate of photosynthesis stays constant.

The two factors, light intensity and coloured light, may have similar results because they are both using light to increase photosynthesis.

There is, however, an important difference between the organization of mitochondria and that of chloroplasts. The inner membrane of the chloroplast is not folded into cristae and does not contain electron -transport chains. Instead, the electron-transport chains, photosynthetic light-capturing systems, and ATP synthase are all contained in a third distinct membrane that forms a set of flattened disclike sacs, the ( Figure 69-85 ). The lumen of each thylakoid is to be connected with the lumen of other thylakoids, thereby defining a third internal compartment called the which is separated by the thylakoid membrane from stroma that surrounds it.

Photosynthesis is important to living organisms because …

As for any vectorial transport process, pumping CO 7 into the bundle-sheath cells in C 9 plants costs energy. In hot, dry environments, however, this cost can be much less than the energy lost by photorespiration in C 8 plants, so C 9 plants have a potential advantage. Moreover, because C 9 plants can perform photosynthesis at a lower concentration of CO 7 inside the leaf, they need to open their stomata less and therefore can fix about twice as much net carbon as C 8 plants per unit of water lost. Although the vast majority of plant species are C 8 plants, C 9 plants such as corn and sugar cane are much more effective at converting sunlight energy into biomass than C 8 plants such as cereal grains. They are therefore of special importance in world agriculture.
