Morphology of Flowering Plants
Welcome to Biology Simplified! In this video, we will be discussing the morphology (external
structure) of flowering plants. Flowering plants, also known as angiosperms, exhibit a wide
variety of structures and forms. They are characterized by the presence of roots, stems, leaves,
flowers, and fruits. Understanding the external structure of plants is essential for their
classification and study.
Root System
The underground part of a flowering plant is the root system. It consists of a primary root, also
known as the radical, which grows into the soil, and lateral roots that branch out from the
primary root. The fibrous root system is a type of root system found in many plants. The main
functions of the root system are absorption of water and minerals from the soil, providing
anchorage to the plant, and protecting the tender apex of the root.
Region of Meristematic Activity
The region of the root called the region of meristematic activity is responsible for cell division
and growth. This region is located a few millimeters above the root cap and contains small, thin-
walled cells with dense protoplasm. These cells continuously divide, leading to the growth of
the root. Proximal to the region of meristematic activity is the region of elongation, where cells
gradually differentiate into different tissues. Finally, the region of maturation is where the cells
of the root fully differentiate into epidermis, cortex, and vascular tissue.
