Sclereids or stone cells are sclerenchymatous cells approximately isodiametrical
The walls of the typical sclereids are thick, lignified, often showing well-marked
stratification and traversed by pit-canals whic
The structural elements of phloem include sieve tubes, companion cells,
phloem parenchyma and secretory cells.
The sieve tube is the conducting element of the phloem.
It is formed from a vertical series of elongated cells, interconnected by
Meristematic tissue is usually composed of cells characterized by
isodiametric form (except in the case of the provascular tissues), by
possessing a protoplast capable of division and a primary cell wall
composed of cellulose.
The epidermis consists of a single layer of cells covering the whole
The epidermis of the root constitutes the piliferous layer and that of
the shoot is a highly differentiated and compact layer of cells.
The epidermal cells in con
