You are working on a forensics team and collect cells from a crime scene. the cells have a cell wall made of cellulose. this sample most likely came from

The plant cells have the cell wall made up of cellulose. In case, a cell represents the presence of cell wall then it is most likely to belong to plant cells.

Other than plant cell fungi as well as some protozoa also possess the cell wall, but the cell wall made up of cellulose is exclusively present in the plant cells.

So, the cell sample collected in this case is most likely came from a plant.

"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."

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
