Vascular tissue that conducts food produced during photosynthesis is the

Vascular tissue that conducts food produced during photosynthesis is the phloem. The phloem is the innermost layer of the bark of trees which contains various specialized cells such as sieve tubes and phloem fibres. The phloem transports soluble organic compounds made during photosynthesis to all the parts of the plants where it is needed.

really dont know just need some points

"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."
