Cell Surfaces Cell wall Plants, prokaryotes, fungi, and some protists Has multiple functions Thickness and chemical composition differs from species to species and among cell types within a plant. In plants, it protects the cell, maintains its shape, prevents excessive uptake of water, and supports the plant against the force of gravity Although animal cells lack a cell wall, they have an elaborate extracellular matrix (ECM) Influences the behavior of the cell
