Like a cell membrane the cell wall helps to protect the cell from harmful forces. But even though plants have a cell membrane and cell wall animal plants only contain a cell membrane. The cell wall is made of non-living material called cellulose and is located outside of the cell membrane. The cellulose is in long chains that is embedded in proteins and other carbohydrates that harden the entire structure. Pores on the cell wall surface allow ions and molecules to enter and exit the cell.
Cilia & Flagells
Cilia is extended from the cell membrane. the look like short hairlike extentions. The cilia moves water past the cell and it also collects foreign objects. Flagella ia also exted from the cell membrane and has a hairlike structure. But the Flagella is important in movement.
