Cell Biology

Compound Microsocpe
The first part of a plant cell wall that forms when the cell is very young is the primary wall, which remains flexible and able to expand as the cell grows. Cells in the soft parts of a plant often only have primary walls, but, after they have finished growing, cell in the parts of a plant which produce structural support (such as the woody parts of trees and shrubs) all a secondary wall outside the first

Between two plant cell walls is a layer, called the middle lamella that helps hold the cells together.
