Identify the parenchyma, xylem, phloem and dermal tissues. Is collenchyma present? _____ Collenchyma will appear as thickened cell walled cells. Unlike the thick cell walled sclerenchyma fibers, collenchyma will NOT stain red with the phloroglucinol stain.

Phloroglucinol is an organic compound with the formula C6H3(OH)3. It is a colorless solid. It is used in the synthesis of pharmaceuticals and explosives. Phloroglucinol is one of three isomeric benzenetriols. The other two isomers are hydroxyquinol (1,2,4-benzenetriol) and pyrogallol (1,2,3-benzenetriol). Phloroglucinol, and its benzenetriol isomers, are still defined as "phenols" acco…
