What do plants release during the process of photosynthesis?

Take a look at the Photosynthesis Animation of the Light Dependent Reactions from the Virtual Cell Animation Collection. You are not required to know the detail in this video, but rather get a feel for the overall process and the roles of the following molecules:

The first stage of photosynthesis takes place inside structures called

This diagram depicts photosynthesis. Photosynthesis is the process in which plants synthesize glucose. The process uses carbon dioxide and water and also produces oxygen. The plant gets energy from sunlight using a green pigment called chlorophyll. Photosynthesis changes light energy to chemical energy. The chemical energy is stored in the bonds of glucose molecules. Glucose is used for energy by the cells of almost all living things. Plants make their own glucose.

These chloroplasts are what color the leaf green and they are the site of photosynthesis.

As was previously discuss, chlorophyll is extremely important in plant’s leaf cells to produce sugars via a process called photosynthesis. This type of pigment is found during most of the plant’s growing season, which is during the spring and summer months. Most plants also contain a pigment called carotenoid, as discussed, which creates a yellow/orange color. This pigment, as well, is found during most of the growing season, but chlorophyll washes out its color, which explains why Sugar Maple leaves are green during the spring and summer months. Unlike most trees, Sugar Maples also contain a pigment called anthocyanin which gives plant leaves a red color. This pigment, unlike the other two, is only expressed in the autumn months and under conditions where the days become shorter, the nights longer, and the temperature drops slowly. As this happens, there is less and less sunlight, causing the tree to produce less chlorophyll until chlorophyll production ceases. As less chlorophyll is made, the other pigments within the leaves can begin to be expressed. The rate at which this happens varies from leaf to leaf in Sugar Maple, so the leaves of one single tree can give a whole assortment of colors at any given time.

The animation is complex because of so many interrelated processes occurring simultaneously.

The Process of Photosynthesis in Plants (With Diagram)

Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

Chlorophyll is a green pigment found in leaf cells giving them their green color. These pigments can absorb light from the sun and use it for photosynthesis. Sugar Maple trees also contain other pigments called carotenoid, which are yellow/orange pigments, and anthocyanins, which are red pigments. The last two pigments are not seen in Maple Trees all times of the year, mostly because chlorophyll is highly expressed the rest of the time essentially washing out the other pigments.

The Process of Photosynthesis in Plants

Sugar Maples, like all plants, are photoautotrophs, meaning they produce their own food from sunlight, carbon dioxide, and water in a process called photosynthesis. By this process, plants can then produce oxygen and organic compounds (mostly sugars). Not only can the plant produce food necessary for it to survive, but it also produces vital oxygen necessary for humans and many other organisms to survive. For a Sugar Maple tree, as for most plants, the leaves are the sites of photosynthesis.


The complex process of photosynthesis actually consists of TWO interrelated complex reactions -- the LIGHT and DARK reactions.

Watch the following video clip from NOVA entitled, 'Earth from Space' to see the impact of photosynthesis on a global scale. While watching, think about why it is that oxygen and carbon cycle from day to night on the planet. (Hint: Both Photosynthesis and Cellular Respiration are reverse processes.)
