Answer :
Choice A i think
B. Cell wall because animal cell has its non-fixed shape and plant cell has fixed shape.
I would think it would be C
Plant A would have one allele from each parent, so the leaf color will be the dominant one.
Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.
Hope it helped,
