In the non-cyclic reaction, the photons are captured in the light-harvesting antenna complexes of photosystem II by chlorophyll and other accessory pigments see diagram at right.
They are present in variable concentrations in nearly all higher plants and many microorganisms such as — red and green algae, photosynthetic bacteria and fungi. As all these external factors act simultaneously on the photosynthetic process, the factor which is in the relative minimum will act as the limiting factor, i.
In your role as a facilitator, you should feel free to share this project with them, but not to do the project for them.
Science Fair Project 4. They are red, orange, yellow and brownish pigments. Sixteen thousand species of plants use CAM. A number of other substances are also produced as the by-products, for example, the oxygen needed by animals and human being continues to be supplied by photosynthesis.
These accessory pigments act as antenna complexes and procure light from different regions of the spectrum than the chlorophyll. Water molecule splits in presence of light.
Carbon dioxide absorbed from air is replaced—by the respiration of plants and animals, decomposition of organic matters, etc. Related Articles:.
These bubbles are oxygen produced by photosynthesis! Some plants have evolved mechanisms to increase the CO 2 concentration in the leaves under these conditions.
