- Photochemical phase or Hill reaction: Previously it was known as light phase. For this phase can be done, plants must absorb light. Plants absorb light through substances called pigments. Among these, there is the chlorophyll, the green pigment that is within the chloroplasts of the plant cell.

Plants cells contain a number of structures that are involved in the process of photosynthesis:

On the other hand, anoxygenic photosynthesis uses electron donors other than water. The process typically occurs in bacteria such as purple bacteria and . “Anoxygenic photosynthesis does not produce oxygen — hence the name,” said , professor of botany at the University of Wisconsin-Madison. “What is produced depends on the electron donor. For example, many bacteria use the bad-eggs-smelling gas hydrogen sulfide, producing solid sulfur as a byproduct.”

Organisms need energy to survive. Some organisms are capable of absorbing energy from sunlight and using it to produce and other organic compounds such as and . The sugars are then used to provide energy for the organism. This process, called photosynthesis, is used by including , , and .


Photosynthesis - definition of photosynthesis by The …

Photosynthesis in green plants harnesses the energy of sunlight toconvert carbon dioxide, water, and minerals into organic compoundsand gaseous oxygen.In addition to the green plants, photosynthetic organisms includecertain protists (such as euglenoids and diatoms), cyanophytes(blue-green algae), and various bacteria.

The process inphotosynthetic protists and cyanophytes resembles that in greenplants; it differs in the photosynthetic bacteria in that compoundsother than water serve as a reactant and oxygen is not produced.

The process by which green plants, ..

Animals eat food to get their energy. But green plants don't. Instead they make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise.

These cells contain a green color component called chloroplast.

The top leaves of crops absorb far more light than they can use, starving lower leaves of light. Scientists designed plants with light green leaves with hopes of allowing more light to penetrate the crop canopy and increase overall light use efficiency and yield. This strategy was tested in a recent modeling study that found leaves with reduced chlorophyll content do not actually improve canopy-level photosynthesis, but instead, conserve a significant amount of nitrogen that the plant might be able to reinvest to improve light use efficiency and increase yield.

Why no photosynthesis takes place in blue color light, ..

There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. Oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
