This oval-shaped drawing was what I saw, with cells overlapping. There was a darker contrast and texture to the surface of the skin sample. Unidentified object in the Freshmen Biology animal sample. A very dark mass of blob that I had no idea what it was. It looked like a black hole - totally dark, with texture on top.
Plant cells are more rectangular, and in blocks.
Animal cells are more oval-shaped, elongated. This is probably somehow related to purpose. I am reminded of how muscle cells look - elongated. The plant cells may have been designed rectangular in order to afford maximum space and efficency for their purposes, while animal cells the same. Which is a rather thin level.
