1. Chlorophyll absorbs light

2. Water split to start electron transport chain

3. ATP produced

4. ATP used to build glucose form carbon dioxide

Explanation:

Photosynthesis is the process whereby green plants synthesize their food (glucose) in the presence of sunlight. This photosynthetic process occurs in two major stages viz: light dependent and light independent phases.

In the light dependent phase, the following occurs sequentially:

- Chlorophyll absorbs light energy from sun

- The energy is used to split water molecule in a process called PHOTOLYSIS OF WATER in order to start electron transport chain.

- The electron transport chain yields ATP and NADPH, which will be used in the next phase.

In the light independent phase, also called, CALVIN CYCLE, ATP is used to power the formation of glucose from carbon dioxide

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
