• B. Cell theory.
• C. Theory of cell lineage.
• D. Nucleus functions as control centre of cell.

Answer 1

The correct option is B Cell theory.

Schleiden and Schwann are associated with proposing the cell theory on the basis of their individual observation of plant and animal cells. Schleiden while studying a large number of plants observed that all the plants are made up of different cells that form the tissues of the plant. Schwann while observing different animal cells observed an outer layer around the cells. he also proposed that the cell wall is the unique characteristic of plants. Together they proposed a cell theory and are thus associated with it.
