Ivo:
Also, why do epidermal cells contain no chloroplasts?
And so it looks like (from past papers) that artery is an organ then. How odd! I thought it was a tissue.
Xylem tubes have no end walls? What are end walls?

end walls is like a barrier that stops smthn from passin ..and in xylem there is no in order to transport water and salts up to the leaves .
nah it is an organ ...but if they point at a part of it then it's a tissue ;)
in order for the palisade cells to receive max light intesity to photosynthesize then the epidermis is transparent hence no chloropasts ;)
got it ?
