What is the 2 division of science and their branches

According to my professor, the two divisions of science are the natural science and physical science. Natural sciences deal with the study of life like biology and other branches of it like botany and zoology. On the other hand, Physical Sciences study matter in a molecular level, unlike the natural sciences which focuses on cells and other small units of lifeforms. Other branches of physical science includes Physics and Chemistry :)
