Chapter 4, Problem 2CT
Summary Introduction
To explain: A secondary cell wall forms on the inner side of the primary cell wall in plants instead of on the outer surface of it.
Concept introduction:
The plants are enclosed by cell wall secreted by extracellular matrix. It is the thin layer formed on the outer surface of the plasma membrane and allows the cell to enlarge during the growth. It is known as the primary cell wall. In some plants, such as woody plants, a secondary cell wall forms on the inner side of the primary cell wall. It is composed of lignin that is found in the xylem walls and fiber cells of woody tissues.

Students have asked these similar questions
In plants, the cell wall forms as a young plant cell secretes polysaccharides onto the outer surface of its plasma membrane. Being thin and pliable, this primary wall allows the cell to enlarge and change shape. At maturity, cells in some plant tissues deposit material onto the primary wall’s inner surface. Why doesn’t this secondary wall form on the outer surface of the primary wall?
Which of these cell junctions are open channels that connect the cytoplasm of adjoining plant cells?
A. Adhering junctions
B. Tight junctions
C. Gap junctions
D. Plasmodesmata
From the image, what is the normal function of the missing structure?
A. A lipid bilayer controlling the movement of substances into and out of the cell
B. A motor protein that "crawls" along microtubules to contract and release them, which provides movement
C. A cytoskeleton element composed of tubulin subunits to provide structure for movement of the cell
