Tertiary cell wall
WebA plant cell wall may have 2 - 3 parts : primary wall, secondary wall and occasionally tertiary wall. Primary wall is thin elastic and contains cellulose, hemicellulose, pectic substances, … WebThis wall may consist of cellulose or mixtures of cellulose, non-cellulosic polysaccharides and hemicelluloses. Sometimes the number of layers of secondary wall may exceed three, and the innermost sometimes only of a helical band and such bands are called tertiary spirals or spiral thickenings (Eames and Mac Daniels, 1947).
