The anatomical features of a monocot root can be studied through a cross section (CS) through the root. The present post discesses the anatomy of monocot root with Monocot Root Diagram. Ø Anatomically, the monocot root has been differentiated into the following parts: (1). Epidermis (2). Cortex (3). […]

It is a complex tissue composed of more than one type of cells namely sieve elements, companion cells, phloem fibres and phloem parenchyma. Among these cells, the sieve elements are the most specialized cells […]

Sclerenchyma: Structure, Classification and Functions
Sclerenchyma is a simple permanent tissue in plants. Sclerenchymatous cells are dead at their maturity. Cells do not have protoplast when they completely developed. They have thick secondary cell wall. The secondary cell wall is lignified and very hard. Most of the sclerenchymatous cells show intrusive growth. The present post […]
