Answer: It is made mostly of cellulose.
Which statement is true about a cell wall but not a cell membrane?

A cell wall is a structural layer surrounding some types of cells just outside the cell membrane. It can be tough flexible and sometimes rigid. It provides the cell with both structural support and protection and also acts as a filtering mechanism. Cell walls are present in most prokaryotes (except mollicute bacteria) in algae fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels preventing over-expansion of the cell when water enters.

A cell wall is the wall of a cell in plants bacteria fungi algae and some archaea. Animal cells do not have cell walls nor do protozoa. Cell walls protect the cells from damage. It is also there to make the cell strong to keep its shape and to control the growing of the cell and plant. The cell wall is the tough usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is outside the cell …

Plasmodesma - Wikipedia

For cells without a cell wall such as animal cells if the gradient is large enough the uptake of excess water can produce enough pressure to induce cytolysis or rupturing of the cell. When plant cells are in a hypotonic solution the central vacuole takes on extra water and pushes the cell membrane against the cell wall. Due to the rigidity of the cell wall it pushes back preventing the cell from …

Formation. Primary plasmodesmata are formed when fractions of the endoplasmic reticulum are trapped across the middle lamella as new cell wall are synthesized between two newly divided plant cells . ...
