LOCATION, SIZE, AND EXTENT TRAN…, Freud, Sigmund 1856-1939 In roots, the hypodermis is often called the exodermis; it resembles the endodermis, and it develops Casparian strips, suberin deposits, and cellulose deposits impregnated with phenolic or quinoidal substances. It is composed of two or three lasers of round and walled thin parenchymatous cells. Most nematodes have lateral, dorsal, and ventral cords that contain nuclei and other cytoplasmic inclusions of the hypodermis. A collection of cells performing a specific function is called tissue.
