Take a look at this picture: http://activity.ntsec.gov.tw/lifeworld/english/content/images/en_gene_c1.jpg It's a side-by-side comparison of an ANIMAL cell, and a PLANT cell. Look at the PLANT cell, on the RIGHT side. Do you see how the plant cell has something called a CELL WALL? Animal cells don't have those.

i would say cell walls.

Cell Walls because plants have cell walls, while organisms has cell membranes!

anonymous · Answer

Plants are organisms. 
Plants ALSO have cell membranes, along with their cell walls. 

I think you meant to say that ANIMALS only have cell membranes, and no cell wall.
