The Old English word "treo" is where the word "tree" first appeared. A tree is a tall plant with an incredibly lengthy lifespan. It has branches that hold up the leaves on a single stem, or trunk. Trees have underground roots that store nutrients and serve as an anchor while also supplying the plant with the water it needs to thrive. Trees make their surroundings better and improve the quality of the air. They thrive in practically any type of setting due to their adaptability.
