Which of the following are not characteristics of the cell wall? select all that apply.
cellulose and chitin
hydrophillic and hydrophobic structures found in cells of fungi and algae
double-layered membrane

hydrophobic and hydrophilic structures found in cells of fungi and algea

double-layered membrane

A cell wall is a a semi-permeable protective layer found in some cell types. This covers the cell membrane in plants cells, fungi, bacteria. Animal cells do not possess cell wall. The cell wall performs functions like protection, provides structural stability to a cell and support. Cell wall composition varies depending upon the type of organism. In plants the cell wall is made up of fibers of carbohydrate polymer called as cellulose. In bacteria cell walls are made up of peptidoglycan. In fungi cell wall is made up of chitin. Hydrophillic and hydrophobic structures found in cells of fungi and algae and double- layered membrane are features of cell membrane not of cell wall.
