Verified step by step guidance1
Understand that the cell wall is a crucial structure in prokaryotes, particularly bacteria, providing structural support and shape.
Recognize that the cell wall is indeed part of the cell envelope, which also includes the cell membrane and, in some bacteria, an outer membrane.
Acknowledge that the cell wall helps prevent the bacteria from bursting by maintaining osmotic pressure balance, especially in hypotonic environments.
Consider the role of peptidoglycan in bacterial cell walls, which provides rigidity and strength, contributing to the shape and protection of the cell.
Conclude that all the statements provided are true, as they accurately describe the functions and characteristics of the prokaryotic cell wall.
