The bark is the equivalent of human skin. It provides 'pathways' for the sap to rise upwards and along branches, stems and leaves. It also provides a certain amount of protection from attacks by animals, birds etc.
The thick bark is fire-resistant so it can survive fires
Redwoods have several adaptations for survival, including thick bark to resist fire and disease, shallow roots to access surface water, and tannins in their wood to deter insects and fungi. Their ability to grow tall allows them to capture sunlight in dense forests, giving them a competitive advantage for light.
The thick bark of a redwood tree helps protect it from fires, insect infestations, and extreme weather conditions. It also helps to retain moisture within the tree, providing a buffer against dry conditions.

Yes, the type of wood does affect of how it burns. Some types of wood have a thick bark which lets thick smoke out. On the other side if it does not have thick bark it won't burn as well as thick bark.
Birch trees have peeling bark as a way to protect themselves from pests and diseases. The outer layers of bark can carry harmful organisms, so shedding the bark helps the tree stay healthy.
Sequoias and redwoods have thick, fire-resistant bark that helps them survive low-intensity fires. In a moderate or severe fire, these trees can still be damaged or killed, but they have adaptations like deep roots and high canopy crowns that increase their chances of survival. After a fire, these trees can resprout from the base or from latent buds in their trunks, allowing them to regenerate and continue growing.
The wood of the tree will burn some what like Pine. But the bark is 6 inches or more thick and has natural flame retardant properties. as long as the wood is not exposed by the bark haven been broken off or there is not a large amount of dry fuel like dead falls next to the base of the tree it will not burn normal brush ans weeds that grow in the area of the trees would not burn a long time and will not degrade the bark to the point that the wood of the tree will start to burn.
Redwoods and sequoias have lived for thousands of years due to several key factors, including their natural resistance to pests and diseases, which helps them avoid many threats that typically shorten the lifespan of other trees. Their thick bark provides protection from fire, allowing them to survive in fire-prone environments. Additionally, they thrive in specific climatic conditions, such as the moist coastal fog of California, which supports their growth and longevity. These adaptations enable them to withstand environmental challenges and continue growing for millennia.
Bark is the outer layer of the living tissue of the tree. As the living layer grows it pushes the bark layer to the outside, which stretches and cracks the bark. Bark protects the tree from things that would harm the living tissue of the tree. Dangers include pests such as beetles and termites, and the heat from fires. Bark also slows the evaporation from the living tissues that would make the sap too thick to travel down to the roots. Without bark, many trees could not survive in the hot, cold, pest infested areas that they live in.
A trunk ;)
Eucalyptus trees have thick bark which protects the inner heart of the tree. The seeds have a shell surronding them, this helps in a fire.
