A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls. The cell wall provides strength and structural support to the cell, and can control to some extent … See more The cell wall has a few different functions. It is flexible, but provides strength to the cell, which helps protect the cell against physical damage. It also gives the cell its shape and allows the … See more 1. Which is a function of the cell wall? A. To maintain turgor pressure B. To provide support to the cell C. To control what molecules enter and … See more WebThe cell wall and cell membrane are not the same thing. All cells have a cell membrane, but not all cells have a cell wall. Cell walls are very rigid, which makes the cell harder to move. They can be made up of a variety of substances, so cell walls in plant cells are different than those found in bacterial cells. gobelins formation continue
