Summary Introduction

To determine:

The effect of impermeability of plant cell wall or the animal extracellular matrix on the cell function.

Introduction:

Extracellular matrix (ECM) is a collection of molecules secreted by cells that provide biochemical and structural support to neighboring cells. The extracellular matrix of animals includes basement membrane and interstitial matrix. The cell wall is a layer that surrounds cells, present outside the cell membrane. The function of the cell wall is to provide protection and support.
