Most leaves are flat and contain chloroplasts; their main function is to convert energy from sunlight into chemical energy (food) through photosynthesis. A plant is a member of the kingdom Plantae, a living organism that utilizes photosynthesis, a process in which energy from sunlight is converted to chemical energy (food). Schoute, J. C. (1938). Following World War II, Katherine Esau published, Plant Anatomy (1953), which became the definitive textbook on plant structure in North American universities and elsewhere, it was still in print as of 2006.

(1947). Such knowledge is important when it comes to taking proper care of the plant, understanding their growth cycle, telling the males from the females and so much more.

There are two main types of root systems: taproot and fibrous. In some species it disintegrates or is crushed; however it remains in other species, such as McGraw-Hill, New York, link (1st ed., 1925, link). The other founder was the British doctor Nehemiah Grew.
