Question

Each of the following is a component of the plant cell wall network except

A) hyaluronate.
B) cellulose.
C) extensin.
D) hemicellulose.
E) pectin.

Answer 1

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.
