If you compare plant and animal cells, you will discover differences. Plant cells are stiff and rigid. They have a(n) cell wall that protects the plant cell. Animal cells have only a thin outer covering called a(n) cell membrane to protect them. Plant cells only have one or two holding bins called vacuoles. Animal cells have many vacuoles. Plant cells have food factories called chloroplasts which animal cells don’t have. Plant and animal cells also have other parts. Both have cell nuclei which are found in the center of the cells. They have a jellylike substance that fills the cells called cytoplasm. Both types of cells also have a part that uses fuel from food for energy. It’s like the cell’s power plant.
