Answer:
The cell's shape depends in part on the structure and composition of the extracellular matrix.
The size that the cell grows to depends in part on the polysaccharides in the extracellular matrix.
Explanation:
The extracellular is a suspension of macromolecules that supports the local tissue growth and maintain organs. The extracellular matrix directs the morphology of a tissue.
The extracellular matrix stores cellular growth factors, which are released locally based on the physiological needs of the local tissue.
The extracellular matrix transduce signals into cells, which regulate cellular functions such as growth, proliferation, migration, differentiation, etc.
