These structures can undergo stress relaxation and an extension called creep that is catalyzed by expansins.
These structures can undergo stress relaxation and an extension called creep that is catalyzed by expansins. Another method of growth of these structures is caused by proton ATPase [A-T-P-"ace"]. Two of these are joined by a middle lamella. A polysaccharide that is highly concentrated in these structures and in the peels of citrus fruits is used to make jellies. A different polysaccharide that is highly concentrated in these structures and cotton is used to make paper; those chemicals are pectin and cellulose. Name these relatively rigid structures not found in protozoa and animals that surround other types of cells.
