Answer:
Cell wall and chloroplasts, if you're comparing them to plant cells.
Explanation:
Plant cells have a harder protective wall around them, harder than the cell membrane. The animal cell doesn't have this.
Chloroplasts are organelles that takes the sunlight and turns it into energy for the plant cell. Animal cells don't have this for obvious reasons. We get our energy from food, not the sun.
The villi can increase the surface area in the small intestine for absorption of digested food. As the villi has a thin wall, one cell thick, which can speed up diffusion, and a network of blood capillaries to absorb and transfer nutrients.
And in large intestine, those folds can also increase the surface area for reabsorption of unabsorbed food, mostly water.
False is the answer I think
