(a) Outline the role of accessory pigments in photosynthesis
More than 10 billion tons ofcarbons are "fixed" by plants on Earth every year- this means that carbon molecules are convertedfrom being part of a simple gas (carbon dioxide)into more complex molecules (carbohydrates),making carbon available as food fornon-photosynthesizers, like humans. They alsoproduce oxygen at the same time. Take a look at atree - most of the mass of that tree was made bythis process of pulling the carbon out of the gasform and into the sugar form. Amazing!
The new role of carbon dioxide in photosynthesis
The fact that much of the ocean is not readily available to take up the additional carbon dioxide introduced through human activities raised a warning flag in the scientific community.
The Mauna Loa monitoring station reports the carbon dioxide level in the atmosphere today as about 380 parts per million compared to 315 ppm in 1958 when modern measurements were initiated. Measurements of air bubbles trapped in the Greenland ice sheet indicate concentrations of 270 ppm in preindustrial times.
More on the Role of Carbon Dioxide
This has led a number of scientists to raise the yet unanswered question of whether the continued addition of carbon dioxide to the atmosphere (which adds acid to the upper ocean) will eventually result in damage to coral reefs.
Pioneering findings on the dual role of carbon dioxide …
This back-pressure effect has the consequence that the ability of the water to hold carbon dioxide increases by only about 1% for each 10% increase of thein the atmosphere.
What Is the Sun's Role in Photosynthesis? | Hunker
CO 2 used during photosynthesis first must pass through stomata into internal spaces within.
It is commonly assumed that they therefore provide the main short-term control of both transpiration and photosynthesis the role of stomata.
C3 Photosynthesis Plants which use only the Calvin cycle for fixing the carbon dioxide from the air are known as C3 plants.
[Role of carbon dioxide hydration in photosynthesis].
Since it constantly disappears by decay, the amount of radiocarbon within the ocean depends on how fast the carbon dioxide from the atmosphere penetrates into the ocean and replenishes the store of radiocarbon there (See Glossary to learn more about and .).
The carbon dioxide molecule is linear and centrosymmetric
Carbon dioxide will form "dry ice" at -78.5ºC (-109.3º F). One kg of dry ice has the cooling capacity of 2 kg of ordinary ice. Gaseous or liquid carbon dioxide, stored under pressure, will form dry ice through an auto-refrigeration process if rapidly depressured.

The carbon dioxide diffuses through small holes in the underside.
