What are two types of cell walls? Choose up to 2 choices.
|
|
PRIMARY CELL WALL-While a plant cell is being formed, a primary cell wall develops just outside the cell membrane. As the cell expands in length, cellulose and other molecules are added, enlarging the cell wall. When the cell reaches full size, a secondary cell wall MAY form.
|
|
|
SECONDARY CELL WALL-The primary cell walls forms between the primary cell wall and the cell membrane. The secondary cell wall is tough and woody, in fact the secondary cell wall is what we call wood. Once a secondary cell wall forms, a plant cell can grow NO further. The cells are dead.
