A tree is a perennial plant with an elongated stem, or trunk, that supports branches and leaves. It can include woody plants with secondary growth, as well as palms, tree ferns, bananas, and bamboos. Trees have evolved to compete for sunlight, growing tall and long-lived. They play a crucial role in reducing erosion, moderating the climate, and providing habitats for various species. However, deforestation for agriculture is causing forests to shrink. There are approximately 3.04 trillion trees in the world, with the highest biodiversity found in South America. Trees can be classified as angiosperms or gymnosperms, with different types of roots, trunks, and leaves. They reproduce using seeds, which exhibit great diversity in size, shape, and dispersal mechanisms. The earliest trees were tree ferns, horsetails, and lycophytes.
