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 definition and cell types of xylem tissue in plants. Definition of Xylem: Xylem can be defined as a complex tissue that is composed of four basic types of cell (tracheids, trachea, and xylem fibre and xylem parenchyma), remains in close association with phloem and has specialized functions like conduction of water and [...]
Sclereids are either oval, rounded or elongated cells with thick Iignified walls that occur singly or in groups in plants. Distribution of Sclereids Cells: Sclereids occur singly or in groups and in association with xylem and phloem in all plant organs. They occur in the aerial roots of Monstera and in the roots of Nymphaea. The stems and petioles of [...]
