Structurally, plant and animal cells are very similar because they are both eukaryotic cells. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles; Plant cells are rectangular wheres animal cells are round.
Well, with animals it depends on the breeding. Along with that, it depends where the animal lives. (Example, Desert or Antarctica.)
For plants, it's basically the same thing. Except, they use seeds.
I hope this helps! (:
