In the stem of monocot there exist three tissue systems —dermal, vascular and ground tissues, which consist of epidermis, vascular bundles and all tissues except the former two respectively. A brief account of the arrangement and structure is given below. Epidermis: Epidermis is more or less like dicots. In contrast to dicot stem, the epidermis is usually devoid of glandular [...]
In this article we will discuss about the arrangements of tissues in leaves. Leaves are generally flat organs and to differentiate the two surfaces different terms are used. The surface that faces the stem upwardly is designated as upper surface or adaxial surface whereas the other surface is the lower or abaxial surface. Anatomically a leaf comprises the usual three [...]
In this article we will discuss about the arrangements of primary tissues in roots. A cross-section of root reveals the epidermis, cortex and vascular cylinder. Epidermis: Epidermis of root is also referred to as epiblema or rhizodermis as it differs from that of shoot in origin, structure and function. Epidermal cells are compactly set, elongated, and thin-walled with thin cuticle [...]
