Explain the distribution of mechanical tissue in plants

Explain the distribution of mechanical tissue in plants.

• Mechanical tissues in plants constitute the tissues that are responsible for supporting the plant above the ground.
• In the non-woody herbaceous plants, parenchyma serves as the mechanical tissue. It is distributed in the cortex, pith and packing tissue in xylem and phloem. In this position they offer support to the stem when turgid and keep it above the ground.
• In woody plants, mechanical tissue consists of collenchyma and sclerenchyma which has more mechanical strength than parenchyma is located in the cortex, pith, phloem and xylem at this position, they provide enough tensile and compressional strength that allows the woody plants to withstand the stresses of the atmosphere.
• Sclerenchyma and collenchyma tissue also form mechanical tissue around the vascular bundles. This allows the vascular bundles to remain open in order to continually transport material within the plant.
