Because of that wall, plant cells are usually rectangular or cube-shaped, like a tiny shipping container for sunlight. Animal cells, on the other hand, are the Spaghetti-Os of the micro-world—round, squiggly, and constantly changing their minds. Your red blood cells look like donuts; your nerve cells look like lightning bolts.
So if you ever feel boxed in, just remember: you’re an animal cell. You have no excuse not to be flexible. And if you feel round and squishy, well, that’s just scientifically accurate.
