Supporting Tissue in Plants
Performance Objectives
Student should be able to:
- Understand the type of supporting system in plants
- Explain the structure and components of supporting tissues in plants
Content
Plants generally are known to possess supporting tissues which give them definite shape, strength, rigidity and resistance against external forces such as wind and water to which they are continuously subjected. A herbaceous stem is kept erect by a combination of turgor of its living cells, inelastic cuticle and supporting tissues.
Types of Supporting Tissue in Plants
The main supporting tissues in plants are parenchyma, collenchyma, sclerenchyma (fibre) and wood (xylem).
