Answer 2

Answer:

an additional layer, called the secondary wall. The middle lamella serves as a cementing layer between the primary walls of adjacent cells.

Explanation:

Plants form two types of cell wall that differ in function and in composition. Primary walls surround growing and dividing plant cells. ... The much thicker and stronger secondary wall (see figure on right), which accounts for most of the carbohydrcellulose

Abstract. Secondary walls are mainly composed of cellulose, hemicelluloses (xylan and glucomannan) and lignin, and are deposited in some specialized cells, such as tracheary elements, fibers and other sclerenchymatous cellsate in biomass, is deposited once the cell has ceased to grow.
