The surface of our body and internal organs is subjected to wear, tear and injury. To protect the inner tissues, the outer lining of the body is covered by a specialized group of cells called epithelium.

The surface of our body and internal organs is subjected to wear, tear and injury. To protect the inner tissues, the outer lining of the body and organs is covered by a specialized group of cells called epithelium. Epithelial tissues can contain a single layer of cells (Simple Epithelium) or many layers(Stratified Epithelium).

Specialized Epithelial Tissue are a class of epithelial tissues that have very specific and specialized functions and structures. This tissue is composed of cuboidal, columnar, ciliated columnar epithelial cells. These are following types: Ciliated Specialized Epithelium This tissue is composed of long, elongated columnar epithelial cells. Each cell bears numerous cilia at the free surface, i.e. known as brush border.

Those plants whose seed contains only one cotyledon or embryonic leaf is known as monocotyledon or simply monocot. In this section, you will learn about characteristics and anatomy of monocot root. Visit this page to learn about dicot root.

Those plants whose seed contains two cotyledon or embryonic leaf is known as dicotyledon or simply dicot. In this section, you will learn about characteristics and anatomy of dicot stem. Visit this page to learn about monocot stem.

Based on the manner of orientation to the main axis of plant and direction of sunlight, leaves in angiosperms can be divided into two types

Growth in plants happens in two stages first new cells are produced, secondly these cells expand via uptake of water by the vacuole. The division of cells doesn’t occur throughout the plant – but only in meristematic regions. Expansion, however, can occur anywhere. Thus, in any plant, there are regions containing young cells, maturing cells and matured cells that have lost the capacity to divide.

The plants whose seeds have only one cotyledon are called dicots. The structure of dicot root varies greatly from that of the monocots. By understanding the structure of dicot root and monocot root, we can make comparisons between them and distinguish them by studying them under a microscope.
