A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape.
Number of cells. The number of cells in plants and animals varies from species to species; it has been estimated that the human body contains around 37 trillion (3.72×10 13) cells, and more recent studies put this number at around 30 trillion (~36 trillion cells in the male, ~28 trillion in the female). The human brain accounts for around 80 billion of these cells.
