In this article we will discuss about:- 1. Origin and Development of Vessel 2. Phylogeny of Vessel. Origin and Development of Vessel: Trachea (or vessel) originates from meristematic cells (Fig. 10.4) that are grouped together in a longitudinal file. The meristematic cells are known as xylem mother cell that develops from procambial cells in the primary xylem. In secondary xylem [...]
In this article we will discuss about the definition and components of phloem tissue in plants. Definition of Phloem: Phloem is a complex tissue or heterogeneous vascular tissue that stores and conducts principally the products of photosynthesis in vascular plants and sometimes adds mechanical strength. Phloem in association with xylem constitutes the vascular bundle and forms the conducting tissue system [...]
In this article we will discuss about the mechanical tissue in plants. This will also help you to draw the structure and diagram of mechanical tissues in plants. The tissue that supports a plant and their growing organs against any deformation and provides mechanical strength is termed as mechanical tissue. Haberlandt (1914) called the mechanical tissue as stereome. Schwendener in [...]
