What is photosynthesis?

1. Process of converting light energy to chemical energy which stores it in the sugar bonds.
2. All the plants need is CO2, H2O, and light energy to make the sugar.
3. Process takes place in the Chloroplasts, specifically using chlorophyll.
4. Takes place primarily in plant leaves, and little to none occurs in stems.
5. Photosynthesis is divided into two sets of reactions: The light-light dependent(light) reactions and the light-independent(dark) reactions.

A. The light reactions rely on colored molecules called pigments to capture the energy of light. The most important pigments are the green chlorophylls, but accessory pigments called the carotenoids are also present, which are yellow or orange.

B.The parts of a chloroplast include the outer and inner membranes, intermembrane space, stroma and thylakoids stacked in grana. The chlorophyll is built into the membranes of the thylakoids.

The energy harvested via the light reaction is stored by forming a chemical called ATP (adenosine triphosphate), a compound used by cells for energy storage. This chemical is made of the nucleotide adenine bonded to a ribose sugar, and that is bonded to three phosphate groups.

Above is the Photosynthesis Song. It explains a lot that you need to know about Photosythesis.

Below is the Photosynthesis process.

Some plants like cacti and pineapples live in extremely hot, dry areas like deserts and can only ope their stomates safely at when the weather is cool. There is almost not chance for them to get CO2 needed for the dark reaction at day time. At night time when they open their stomates and take CO2 in they use the CO2 into different organic compounds to store it. In the day when the light reaction is occurring the ATP is availabe so they take the CO2 from the compounds and put them into the Calvin cycle. These types of plants are called CAM plants which stands for Crassulacean acid metabolism.

What's involved in photosynthesis is the overall chemical reaction 6CO2 + 6H2O (+ light energy) à C6H12O6 + 6O2.
