Vedclass · Answer

(A) The correct matches are as follows:$(1)$ Robert Brown discovered the nucleus in the cell, so $(1-S)$.$(2)$ Rudolf Virchow proposed that all cells arise from pre-existing cells (Omnis cellula-e cellula), which gave the final shape to the cell theory, so $(2-P)$.$(3)$ Hans Christian Gram developed the Gram staining method to differentiate bacteria, so $(3-Q)$.$(4)$ $J$.$D$. Robertson proposed the unit membrane concept, which suggests that all cellular membranes have a similar structure, so $(4-R)$.Therefore, the correct sequence is $(1-S), (2-P), (3-Q), (4-R)$.

Column $X$	Column $Y$
$(1)$ Robert Brown	$(P)$ Final shape of cell theory
$(2)$ Virchow	$(Q)$ Bacterial staining method
$(3)$ Gram	$(R)$ Unit membrane concept
$(4)$ Robertson	$(S)$ Discovery of nucleus
