What Do Plants Need to Carry Out Photosynthesis? | Hunker

Cabbage leaves are part of the flower, not thephotosynthesizing part of the plant. Also, justbecause they have anthocyanin pigments that makethem purple, they still also have chloroplastswith chlorophyll as well, just less of it. It'snot the green color that allows plants tophotosynthesize; it's the presence ofchlorophyll, which just happens to be green,which is why most plants are green without anyother pigments.

Do all parts of plants carry out photosynthesis? - Quora

what pigments do plants use to carry out photosynthesis?

When do plant cells carry out photosynthesis? | Yahoo …

The drawback to C4 photosynthesis is the extra energy in the form of that is used to pump the 4-carbon acids to the bundle sheath cell and the pumping of the 3-carbon compound back to the mesophyll cell for conversion to PEP. This loss to the system is why C3 plants will outperform C4 plants if there is a lot of water and sun. The C4 plants make some of that energy back in the fact that the rubisco is optimally used and the plant has to spend less energy synthesizing rubisco.

Do both plants and animals carry out photosynthesis …

C3 plants have the disadvantage that in hot dry conditions their photosynthetic efficiency suffers because of a process called . When the CO2 concentration in the drops below about 50 ppm, the catalyst that helps to fix carbon begins to fix oxygen instead. This is highly wasteful of the energy that has been collected from the light, and causes the rubisco to operate at perhaps a quarter of its maximal rate.

We also have to be careful when studying green plants because in the light the green parts of these plants carry out photosynthesis as well as respiration.

What is photosynthesis? - eschooltoday

Yes, we usually think of plants being green. Itsounds like you know that the green pigmentchlorophyll is important in photosynthesis. Whatmight be news is that there are actually manypigments that can trap light forphotosynthesis.

Photosynthesis: Photosynthesis means “making with light”

The acidity was found to arise from the opening of their stomata at night to take in CO2 and fix it into malic acid for storage in the large vacuoles of their photosynthetic cells. It could drop the pH to 4 with a malic acid concentration up to 0.3M . Then in the heat of the day, the stomata close tightly to conserve water and the malic acid is decarboxylated to release the CO2 for fixing by the Calvin cycle. PEP is used for the initial short-term carbon fixation as in the , but the entire chain of reactions occurs in the same cell rather than handing off to a separate cell as with the C4 plants. In the CAM strategy, the processes are separated temporally, the initial CO2 fixation at night, and the malic acid to Calvin cycle part taking place during the day.

12 Answers - Do all plants use photosynthesis? - Quora

These intermediates are characterized by their resistance to so that they can operate in higher temperatures and dryer environments than . At right, the ranges of CO2 compensation points for the three types of plants are shown. These compensation points are the values at which the plants cease to provide net photosynthesis.

Photosynthesis does the opposite of respiration. Carbon dioxide is absorbed and oxygen is produced. In order to study respiration in green plants we must block out the light, because although green plants respire all the time they only photosynthesize in the light.

The connection to hot and dry conditions comes from the fact that all the plants will close their stomata in hot and dry weather to conserve moisture, and the continuing fixation of carbon from the air drops the CO2 dramatically from the atmospheric concentration of nominally 380 ppm (2004 value). If the CO2 compensation point is lower on the above scale, the plant can operate in hotter and dryer conditions. The limits are placed by the fact that begins to fix oxygen rather than CO2, undoing the work of photosynthesis. C4 plants shield their rubisco from the oxygen, so can operate all the way down to essentially zero CO2 without the onset of photorespiration.
