    Everything that is alive is made of one or more cells. The cell is the smallest unit of life, and there are two main types:

    • Eukaryotes = the more complex cells of animals, plants, fungi, protozoans, algae, and slime and water molds

    Although eukaryotic cells share many characteristics, there are also specializations that make plant cells unique. The following is a rundown of the main features differentiating plant cells from other eukaryotes.

    Structures Present in Plant Cells & Absent in Animal Cells

    • Cell wall: Plant cells have protective cell walls, composed mainly of structural carbohydrates. The cell wall provides support, helps maintain cell shape, and prevents the cell from taking on too much water and bursting. The cell wall is not a feature unique to plants; bacteria, fungi and some protists also have cell walls. But unlike the cell walls of bacteria and fungi, plant cell walls are composed of different types of carbbohydrates—cellulose and hemicellulose—and structurally consist of three layers; an outer primary cell wall, a sticky pectin layer called the middle lamella, and a secondary cell wall, closest to the plasma membrane.

    Turgor pressure or turgidity is the pressure of the cell contents against the cell wall, in plant cells, determined by the water content of the vacuole, resulting from osmotic pressure.
