Final answer:
Hyaluronate is not a component of the plant cell wall network; it is found in animal cells. Cellulose, pectin, hemicellulose, and lignin are the actual components of plant cell walls.
Step-by-step explanation:
The component that is not a part of the plant cell wall network is A) hyaluronate. The primary cell wall of plants consists of cellulose fibers embedded in a matrix of water-absorbing pectins and hemicellulose. Many plant cells also develop a secondary cell wall that contains cellulose and lignin, a complex, phenolic polymer which provides substantial compressive strength. Hyaluronate, on the other hand, is not a constituent of plant cell walls; it is found in the extracellular matrix of animal cells.
