Question

How does a tree grow? Explain in detail

Answer 1

in botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.

Answer 2

Trees grow in height as a result of meristems that are located at their branch tips. These meristems are called apical meristems. ... The vascular cambium produces new xylem and phloem each year and as a result, the trunk, branches, and roots continue to increase in diameter.
