Q: How does photosynthesis occur in plants that are not obviously.

As you may know, plants use light to turn carbon dioxide into sugars necessary for growth in a process called photosynthesis. Sunlight has the full spectrum of different wave lengths of light that represent each possible color of light; this is why when we look through a prism we can see all of the bands of color present in the spectrum: red, orange, yellow, green, blue, indigo and violet. Plants use different colors, which represent different wavelengths, of light for different purposes. Plants appear green to us because they reflect green light rather than absorbing it. In other words, plants don´t use green light for any purpose. The most important colors/wavelengths of light are red and blue light.

Algal photosynthesis account for almost half of the photosynthetic carbon fixed every year.

It all depends on the particulars of the light available for photosynthesis, the process by which plants convert sunlight into energy. Photosynthesis produces oxygen and ultimately provides the basis for most life on Earth. []

These chemicals arecritical in the controlling the timing and activity of physiological processes.

During the spring and summer the leaves have served as factories where most of the foods necessary for the tree's growth are manufactured. This food-making process takes place in the leaf in numerous cells containing chlorophyll, which gives the leaf its green color. This extraordinary chemical absorbs from sunlight the energy that is used in transforming carbon dioxide and water to carbohydrates, such as sugars and starch.

Every autumn we revel in the beauty of the fall colors. The mixture of red, purple, orange and yellow is the result of chemical processes that take place in the tree as the seasons change from summer to winter.

Plantsuse a process called photosynthesis to make food. During photosynthesis,plants trap light energy with their leaves. Plants use the energyof the sun to change water and carbon dioxide into a sugar called glucose.Glucose is used by plants for energy and to make other substances likecellulose and starch. Cellulose is used in building cell walls. Starchis stored in seeds and other plant parts as a food source. That's why somefoods that we eat, like rice and grains, are packed with starch!

But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.

Photosynthesis | Definition of Photosynthesis by …

Algae are a very diverse group of predominantly aquatic photosynthetic organisms that account for almost 50% of the photosynthesis that takes place on Earth. Algae have a wide range of antenna pigments to harvest light energy for photosynthesis giving different types of algae their characteristic colour. Early work done with algae contributed much to what is presently known about the carbon dioxide fixation pathway and the light harvesting reactions. The processes of photosynthesis in algae and higher plants are very similar. From among the three types of carbon dioxide‐concentrating mechanisms known in photosynthetic organisms, two types are found in different types of algae. Algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment. Recently, algae are recognized as a promising biodiesel source due to its efficient absorption and conversion of solar energy into chemical energy.

One of the most important ways is through photosynthesis

So a plant can get more energy if it gets more light from the purple end of the spectrum than if it gets the same amount of light from the red end of the spectrum. This means more photosynthesis and more growth.

Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light. They also have a red pigment called phycoerythrin that absorbs green light and extends the range of photosynthesis. The red pigment is found in vegetables. Some red algae are in fact nearly black, so that increases their photosynthetic efficiency. Brown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range. These red and brown algae grow to depths around 270 meters where the light is less than 1% of surface light.

Chlorophylla-a is the primary for in plants. Its structure is shown at left. It has the composition C55H72O5N4Mg. It exhibits a grass-green visual color and absorption peaks at 430nm and 662nm. It occurs in all photosynthetic organisms except photosynthetic bacteria.

Through the process of photosynthesis, sun light is absorbed by plants and converted into chemical energy. Using that chemical energy, the plants are then able to absorb carbon dioxide from the atmosphere and turn it into food for themselves. A beneficial byproduct of that food production is oxygen, which humans need in order to breathe. Photosynthesis will occur in plants, algaes, and different species of bacteria, and organisms that can perform photosynthesis are referred to as photoautotrophs, meaning they can create their own food. Photosynthesis is vital to life on Earth as it helps maintain normal levels of oxygen in the air which is necessary for survival of most species.
