It was not until 1838 that the botanistMatthias Jakob Schleiden, interested in plantanatomy, stated that the lower plants all consist of one cell, while the higher ones are composed of (many) individual cells. When the physiologistTheodor Schwann, Schleidens friend, extended the cellular theory to include animals, he thereby brought about a rapprochement betweenbotanyandzoology. 6 What are the three scientists contributed to the cell theory? 1833 - Brown descibed the cell nucleus in cells of the orchid.
