One of the most important functions of the stem is to give support to the plant.
It creates turgor pressure in the plant. It is internal hydrostatic pressure, which keep the plant rigid and resistant to bending.
The collenchymas and schlerenchyma are heavily lignified cells present in the cortex and xylem tissues respectively. They also give support to the plants. In many terrestrial plant these cell provide support to the plant in win and mechanical stress.
Vascular bundle containing the xylem tissues and it is the tough and inextensible tissues.
The arrangement in the ring provides support to the plant from wind and weight.
Bundle cap present in the plant stem for example in sun flower, the vascular bundle are strengthened by additional schlerenchyma fibres, which form bundle cap.
Schlerenchyma have thick secondary cell walls usually impregnated with lignin and organic substances that makes the walls tough and hard.
Most of the schlerenchyma cells are non living. Their primary function is to provide support to the plant parts.

Stem provided to the plant is by turgidity due to the presence of water in thin walled parenchymatous tissues and thick walled collenchyma and dead tissues like sclerenchyma  and vascular bundled.
