a growing tree is chemical or phycal change..??

 

Growth of a tree is both a physical change as well as a chemical change. This is because growth of a tree involves changes in overall shape and size of the tree (tree on growing becomes bigger in size and its branches spread out). So, it is a chemical change. Also, growing of a tree is a biochemical process which is regulated by plant hormones and enzymes, because of which it is also a chemical change.
