Which scientists proposed the cell theory?
Answer and explanation
Correct answer: D. Schleiden and Schwann
- Step 1: Classical cell theory states that all living organisms are composed of one or more cells, and that the cell is the basic structural and functional unit of life.
- Step 2: In 1838ā1839, German botanist Matthias Schleiden and German zoologist Theodor Schwann independently synthesized their observations of plant and animal tissues to formally propose the unified cell theory.
Answer
Schleiden and Schwann.
Why not the others: 'Hooke and Brown' refers to Robert Hooke (who discovered and coined the term 'cell' in 1665) and Robert Brown (who discovered and named the cell nucleus in 1831); 'Watson and Crick' elucidated the double-helix structure of DNA in 1953; 'Mendel and Morgan' founded classical transmission genetics through pea experiments and Drosophila linkage mapping.
