Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.

Photosynthesis, a process through which plants produce their food, is of utmost importance to us humans and other living beings. A proper and indepth knowledge about this pivotal process will help you understand and preserve our beautiful environment in the long run. Click on the links below to load yourself with useful information regarding this naturally occuring chemical process, certainly the most important process that we know.

Chlorophyll is a green pigment found in cyanobacteria and the chloroplasts of algae and plants.

2014-12-16 12:04:44 UTC

Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.

LEAH THOMAS .Photosynthesis is the physico-chemical process by which plants, algae and photosynthetic bacteria use light energy to drive the synthesis of organic compounds. In plants, algae and certain types of bacteria, the photosynthetic process results in the release of molecular oxygen and the removal of carbon dioxide from the atmosphere that is used to synthesize carbohydrates (oxygenic photosynthesis).

The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or hydrogen sulfide as sources of electrons, rather than water.

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances such as water, producing oxygen gas. Furthermore, two further compounds are generated: reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells

Photosynthesis is
the chemical change which happens in the leaves of green plants. It is the first
step towards making food - not just for plants but ultimately every animal on
the planet.

During this reaction, carbon dioxide and water are converted into
glucose and oxygen. The
reaction requires light energy, which
is absorbed by a green substance called chlorophyll.

Photosynthesis takes place in leaf cells. These contain chloroplasts, which
are tiny objects containing chlorophyll.

Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll.

Light energy is absorbed by the green chemical chlorophyll. This energy allows the production of glucose by the reaction between carbon dioxide and water. Oxygen is also produced as a waste product.

This reaction can be summarised in the word equation:

Carbon dioxide + water glucose + oxygen

Photosynthesis - Higher tier

The chemical equation for photosynthesis is:

6CO₂ + 6H₂O C₆H₁₂O₆ + 6O₂

Plants breathe carbon dioxide just like we breathe oxygen.

2014-12-16 12:32:05 UTC

Not all of the light from the Sun makes it to the surface of the Earth. Even the light that does make it here is reflected and spread out. The little light that does make it here is enough for the plants of the world to survive and go through the process of photosynthesis. Light is actually energy, electromagnetic energy to be exact. When that energy gets to a green plant, all sorts of reactions can take place to store energy in the form of sugar molecules.

Remember we said that not all the energy from the Sun makes it to plants? Even when light gets to a plant, the plant doesn't use all of it. It actually uses only certain colors to make photosynthesis happen. Plants mostly absorb red and blue wavelengths. When you see a color, it is actually a color that the object does NOT absorb. In the case of green plants, they do not absorb light from the green range.

Part II: The Chloroplast

We already spoke about the structure of chloroplasts in the cells tutorials. We want to reinforce that photosynthesis happens in the chloroplast. Within this cell organelle is the chlorophyll that captures the light from the Sun. We'll talk about it in a bit, but the chloroplasts are working night and day with different jobs. The molecules are moved and converted in the area called the stroma.

Part III: The Molecules

Chlorophyll is the magic compound that can grab that sunlight and start the whole process. Chlorophyll is actually quite a varied compound. There are four (4) types: a, b, c, and d. Chlorophyll can also be found in many microorganisms and even some prokaryotic cells. However, as far as plants are concerned, the chlorophyll is found in the chloroplasts. The other big molecules are water (H₂O), carbon dioxide (CO₂), oxygen (O₂) and glucose (C₆H₁₂O₆). Carbon dioxide and water combine with light to create oxygen and glucose. That glucose is used in various forms by every creature on the planet. Animal cells require oxygen to survive. Animal cells need an aerobic environment (one with oxygen).

Part IV: Light and Dark Reactions

The whole process doesn't happen all at one time. The process of photosynthesis is divided into two main parts. The first part is called the light dependent reaction. This reaction happens when the light energy is captured and pushed into a chemical called ATP. The second part of the process happens when the ATP is used to make glucose (the Calvin Cycle). That second part is called the light independent reaction.

Photosynthesis captures energy for life on Earth. Many chemicals are made to allow life processes to occur in plants. These chemicals can move in and out of cells by the process of diffusion. Osmosis is a specific type of diffusion.

Photosynthesis

Light energy is absorbed by the green chemical chlorophyll. This energy allows the production of glucose by the reaction between carbon dioxide and water. Oxygen is also produced as a waste product.

This reaction can be summarised in the word equation:

Carbon dioxide + water glucose + oxygen

Photosynthesis - Higher tier

The chemical equation for photosynthesis is:

6CO₂ + 6H₂O C₆H₁₂O₆ + 6O₂

Glucose from photosynthesis

Glucose is made up of carbon, hydrogen and oxygen atoms. Glucose made by the process of photosynthesis may be used in three ways:

It can be converted into chemicals required for growth of plant cells such as cellulose
It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it
It can be broken down during the process of respiration, releasing energy stored in the glucose molecules

Plants cells contain a number of structures that are involved in the process of photosynthesis:
