All living things are made of cells, the basic building blocks of life. Both plant and animal cells share a nucleus (which controls the cell), cytoplasm (a jelly-like substance where reactions happen) and a cell membrane (which controls what enters and exits). Plant cells additionally have a rigid cell wall for support, chloroplasts for photosynthesis, and a large central vacuole for storage.
Example
Under a microscope, you can tell a plant cell from an animal cell because the plant cell has a distinct rectangular outline (the cell wall) and green chloroplasts, while the animal cell has an irregular round shape with no wall.
