A disease infects an organism, causing the organism's cells to have less chloroplasts. How will the organism be impacted by having less chloroplasts? The organism will have less chlorophy reducing its ability to collect energy
The organism will have less cellulose, reducing its ability to remove waste
The organism will absorb less oxygen, reducing its ability to produce sugar
The organism will absorb less water, reducing its ability to create DNA

the organism will have less chlorophyll

Explanation:

chloroplasts contain chlorophyll

Chlorophyll is a green pigment, without it a plant is discolored meaning it lacks of chlorophyll. Less photosynthesis would occur, and less glucose is made as a result. There is less energy released for growth as glucose is needed for respiration.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

"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."
