what type of cell is responsible for contact dermititis and tissue rejection?
The T lymphocytes are responsible for the contact dermatitis.
When contact dermatitis occurs the allergen is processed by the langerhans cell in the skin and isade available to the T lymphocytes which then causes the hypersensitivity reaction
They also plays a main role in tissue rejection (mainly CD8 subtye of T lymphocytes)
Hope this helps.... Thank you!!!

What tissues/cell types contribute to a plant's ability to grow taller? Choose several tissue/ cell types and for each type you choose, explain how it contributes to a plant's ability to grow taller. (Challenge: on a separate piece of paper (to have more room) try taking every cell type and, in clear and logical steps, explain how a plant could not grow taller without this cell type).

You have a cell that is is contact inhibited in its wild-type form. However, after you insert an oncogene into a target gene in the cell's genome, the cell is no longer contact inhibited. Describe two methods you can use to attain this target gene. (Gene does not have mRNA).
