In this article we will discuss about the significance of root stem transition. During vascular transition there is a reorientation of primary xylem and primary phloem. The reorientation of primary vascular tissues commonly takes place in the hypocotyl of the embryo in provascular strands. Transition regions have their own specific orientation of vascular tissues. This orientation cannot be compared with [...]
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 stem there exist three tissue systems — dermal, vascular and ground tissue, which respectively consist of epidermis, vascular bundle and all tissues except the former two. A great diversity is observed in the arrangement and structure of primary tissues, a brief account of them that commonly occur in mature stems of dicot is mentioned below beginning from the periphery [...]
