The limiting factors of photosynthesis

There have been previous hints, however, that the chloroplasts in the slug don’t run on stored-up supplies alone. Starting in 2007, Pierce and his colleagues, as well as another team, found several photosynthesis-related genes in the slugs apparently lifted directly from the algae. Even unhatched sea slugs, which have never encountered algae, carry “algal” photosynthetic genes.

What is the factor which is limiting the rate of photosynthesis at point X on the graph?

Actually, the ancient ones separated the carbon-hydrogen fuel from the oxygen. The modern trees consist of this fuel which re-joins with the oxygen afterlife. But why didn't this happen to the ancient plants? Where did the ancient carbohydrates go? If it is the oil and gas we can burn it. Why do you say that we do not have enough fossils to burn all the oxygen? Where are the ancient plant bodies deposited so securely that we say for sure that they cannot come back into the contact with the oxygen?

If I understand it right, you are assuming that in the beginning we had CO2, which was then split to organic carbon and O2 via photosynthesis. And now you are asking if it's possible to reverse all of that by burning all organic carbon, so that it consumes the O2.

In plants, photosynthesis occurs mainly within the . Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves. Carbon dioxide is obtained through tiny pores in plant leaves called stomata. Oxygen is also released through the stomata. Water is obtained by the plant through the roots and delivered to the leaves through .

The rate of photosynthesis is high at wavelengths when the absorption by the pigment is low.

“This could be a fusion of a plant and an animal — that’s just cool,” said invertebrate zoologist John Zardus of The Citadel in Charleston, S.C.

The slugs can manufacture the most common form of chlorophyll, the green pigment in plants that captures energy from sunlight, Pierce reported January 7 at the annual meeting of the Society for Integrative and Comparative Biology. Pierce used a radioactive tracer to show that the slugs were making the pigment, called chlorophyll a, themselves and not simply relying on chlorophyll reserves stolen from the algae the slugs dine on.

Commentary: In any question on limiting factors, the factor on the X axis remains a for as long as the graph continues to rise; in this case the point at which it levels off. At this point photosynthesis may still be limited by other factors such as temperature or carbon dioxide concentration.

In other words, most of the carbon that has resulted from photosynthesis is no longer accessible for burning, and consequently not available to react with the atmospheric oxygen.

Sunlight is absorbed by chlorophyll, a green pigment located in structures called . Chloroplasts are the sites of photosynthesis. Chloroplasts contain several structures, each having specific functions:

Your question about using up all of the oxygen in the atmosphere by burning all fossil fuels is a good one. If indeed you could get hold of all of the carbon that, over the past 2 billion years, has been separated from the oxygen by photosynthesis, then you could do that. But the carbon is not accessible: only a small fraction is actually in the form of fossil fuels. A much larger part is simply dispersed in the form of organic matter in the sediments of the earth (both on land and in the sea), and it may not be concentrated enough to actually burn by itself. For example, soil has a significant fraction of carbon, but it does not usually burn. More carbon has been subducted in sediments through plate tectonics and now resides dozens or hundreds of kilometers down in the Earth mantle. (A fraction of it will eventually come back out as carbon dioxide in volcanic eruptions).

Photosynthesis occurs in two stages. These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.

With the advent of scientific forest management and the planting of millions of trees, the State's battered forest lands began to recover. In the 1930s, years of drought resulted in the national climate crisis known as the dustbowl - which coincided with the Great Depression. Even in New York, farms failed from drought, and millions of agricultural acres were abandoned. Some of this land was so poor that literally nothing could grow on it. Many of these abandoned farms, once little more than windblown sand, are now thickly wooded State Forests, transformed by the State Conservation Department (now the Department of Environmental Conservation) and the tree-planting of Franklin D. Roosevelt's remarkable program, the Civilian Conservation Corps (CCC), which provided employment for millions of young men during the Depression.
