chloryphll: The energy that is absorbed of the photon is transferred to an electron in a process called charge separation.

ATP: is a product of the first stage of photosynthesis, and it provides energy for the second stage. energy transfer; that is, ATP is able to store and transport chemical energy within cells.

chloroplast: contains the molecule chlorophyll, which absorbs sunlight for photosynthesis.

stomoata: control the flow of gases in and out of leaves.

Thylakoid: A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.  surrounded by a lunon.

stroma; involved in the Calvin Cycle – carbon fixation, reduction and regeneration. the stroma the supportive tissue of an epithelial organ, tumor, gonad, etc.

Q2: oxygenic photosynthesis and anoxygenic photosynthesis.

Q3: The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

Q4: water, light and carbon dioxide, while the products are oxygen and sugars.

Q5: carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water

CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O
