Q. Cell theory was proposed by

Chhattisgarh PMTChhattisgarh PMT 2005

Solution:

Cell theory was proposed by two German scientists, a Botanist M J Schleiden $(1838)$ and a Zoologist T Schwann $(1839)$. They gave the concept that 'all living organisms are composed of cell'. According to modern cell theory
(i) All organisms are composed of one or more cells.
(ii) Cells are the basic living units within organisms, and the chemical reactions of life take place within the cells.
(iii) All cells arise from preexisting cells.
