I think it's Spain's lucky year now.  And also, are scaly skin and scales the same thing?  About the reptile question.

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 ?

How about this question.  The answer in the mark scheme from this paper and the same from s03, have completely different answers.  I'm clueless.
