Plant world is separated into Vascular and Non–vascular plants
The plant world is conveniently separated into two major groups:
- non–vascular plants
- vascular plants
Highly specialized tissues occur in the vascular plants. (A tissue is a group of cells working together to carry out a specialized function.) The tissues are organized into specialized organs called roots, stems, and leaves. The organs all contain the internal vascular system and are connected to one another by the system. The internal vascular system is composed of xylem and phloem.
Different combinations of tissues make up the organs of a vascular plant. In vascular plants, four types of tissues may be found: (i) vascular tissue, (ii) ground tissue, (iii) dermal tissue, (iv) meristematic tissue.
