They can also be wrapped or rolled around foods, stuffed like sandwiches, or eaten plain. Almost every culture with access to grain has devised some kind of bread that is flat, made from ingredients like wheat, teff, corn, rye, or rice. The most basic flatbread is made from ground grain and water.
Animal cells only have the cell membrane. The cell membrane is a semi-permeable covering surrounding the outside of the cell. Plant cell membranes are found on the outside of the cell cytoplasm and just inside the cell wall. So, the answer to the question, 'Do plant cells have a cell membrane?', is 'Yes!'.
Cell Walls and the Extracellular Matrix. Although cell boundaries are defined by the plasma membrane, many cells are surrounded by an insoluble array of secreted macromolecules. Cells of bacteria, fungi, algae, and higher plants are surrounded by rigid cell walls, which are an integral part of the cell. Although not encased in cell walls, animal cells in tissues are closely associated with an extracellular matrix composed of proteins and polysaccharides.
