Sclereid initials are distinguishable from neighboring cells by their large centralized nuclei. During the younger stages of development, they are densely cytoplasmic and have an abundance of cellular organelles—mitochondria, endoplasmic reticulum, Golgi bodies, and ribosomes. In maturing sclereids, plastids occur infrequently and have few inner membranes, and the nuclei display unique undulations. Secondary wall synthesis occurs during maturation or with the cessation of apical intrusive growth of branches. The secondary wall differs from the primary wall by its hyaline region, homogeneous and electron‐translucent appearance and presence of numerous pit canals.
