Question

Compare and contrast the extracellular matrix of animals and the cell wall of plants. Consider their functions and the types of molecules that make up these structures. What properties of these molecules help to fulfill these functions?

Answer 1

Extracellular Matrix of animal cells:

Chemical components: These are composed of glycoproteins or polysaccharide moyeity of particular tissue.

Origin: These are basically originates from secretory components of the cells.

Diameter: Extracellular matrix is basically very thin, on which the cells are lining to forum a particular structure.

Fibre contents: Fibre is containing fibrous protein.

Occurrence: Particular cell type or tissue are characterized with particular extracellular matrix. It is always found with multicellular animal cell colony.

Cell wall of plant cell:

Chemical components: These are composed of cellulose, hemicellulose mainly which are polysaccharides in nature.

Origin: Cell wall originates at the time of plant cell division through the deposition of components on both sides of the middle lamella.

Diameter: Based on the plant cell age the cell wall thicken in aged cells. Primary and then secondary thickening occurs in cell wall.

Fibre: Fibre is made up of cellulose prothecated in pectin base.

Occurrence: Cell wall in plant cells are always found in unicellular to multicellular cells.
