 * ===The Cell wall is tough,usually flexible but sometimes fairly rigid layer that surrounds some types of cells ===
 * === Cell wall are made of specialized sugars called cellulose ===
 * ===There are small holes in the wall that let nutrients,waste,and ions pass through ===
 * === The holes are called plasmodesmata ===
 * ===Cell walls consist of 3 layers ===
 * ===The 3 layers of a cell wall are the middle lamella,primary wall,secondary wall ===
 * ===The middle lamella is the first layer formed during cell division and it makes up the outer wall of the cell ===
 * ===The primary wall is formed after the middle lamella and consists of a rigid skeleton cellulose microfibrils embedded gel-like matrix composed of pectic compounds, hemicellulose,and glycoprotiens ===
 * ===The secondary wall is a thick layer rich in lignin that strengthens and waterproofs the wall and is formed inside the primary cell wall that has stopped increasing in surface area when the cell is fully grown media type="youtube" key="Yu21ShnKhHk" height="315" width="420"===
