Vedclass · Answer

(A) The correct matches are as follows:$1.$ Robert Brown discovered the nucleus in $1831$ $(1-s)$.$2.$ Rudolf Virchow explained that cells divide and new cells are formed from pre-existing cells ($Omnis$ $cellula-e$ $cellula$), which gave the final shape to the Cell Theory $(2-p)$.$3.$ Hans Christian Gram developed the bacterial staining method, known as Gram staining $(3-q)$.$4.$ $J.D.$ Robertson proposed the unit membrane concept for the structure of the plasma membrane $(4-r)$.Thus, the correct sequence is $(1-s), (2-p), (3-q), (4-r)$.
