Verified step by step guidance

Identify the main components of a plant cell wall, which are primarily carbohydrates such as cellulose, hemicellulose, and pectin.

Recognize that the extracellular matrix (ECM) of animal cells is composed of proteins like collagen, elastin, and glycoproteins, rather than carbohydrates.

Understand that both plant cell walls and animal cell ECMs are permeable to water and small solutes, allowing for the exchange of substances necessary for cellular function.

Note that collagen is a major component of the animal cell ECM but is not a significant component of plant cell walls.

Conclude that the common characteristic between plant cell walls and animal cell ECMs is their permeability to water and small solutes, as both structures facilitate the movement of these substances.
