Introduction!

On here you will read about what Photosynthesis is, how it works, all the 3 steps of Photosynthesis. And what a Chloroplast is! Hope you enjoy!

What is Photosynthesis?

Photosynthesis is the process by which light energy turns into chemical energy. The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

How does it work?

Step 1. Absorption! Photosynthesis depends on the absorption of light by pigments in the leaves by plants. The most important of these is Chlorophyll but there are several accessory pigments that also contribute. The measured rate of Photosynthesis as a function of absorbed wavelength correlates well with absorption frequencies of Chlorophyll a, but makes it evident that there are some other contributors to the absorption. Step 2. Electron Transport in Photosynthesis. Both Photosynthesis 1 and 2 are utilized to split water to get electrons. Electron transport helps establish a protein gradient that powers ATP production and also stores energy in the reduced coenzyme NADPH. This energy is used to power the Calvin Cycle to produce sugar and other carbohydrates. Step 3. The Calvin Cycle. In the stroma using electrons carbon enters as CO2 and leaves as sugar.

The Chloroplasts!

A chloroplast is an organelle unique to plant cells that contains chlorophyll (which is what makes plants green) and is responsible for enabling photosynthesis to occur, so that plants can convert sunlight into chemical energy. So basically, without chloroplasts, plants could not create energy, and without them, humans would have no food and we would perish, so thank you chloroplasts!
