Match List I with List II. List-I: A. Fleming B. Robert Brown C. George Palade D. Camillo Golgi List-II: I. Disc-shaped sacs near nucleus II. Chromatin III. Ribosomes IV. Nucleus
Answer & NCERT explanation
Correct answer: D — A–II, B–IV, C–III, D–I
Fleming discovered chromatin (A-II), Robert Brown discovered nucleus (B-IV), George Palade discovered ribosomes (C-III), and Camillo Golgi discovered disc-shaped sacs near nucleus - Golgi apparatus (D-I). These are fundamental discoveries in cell biology by respective scientists.

Nucleus as a cell organelle was first described by Robert Brown as early as 1831. Later the material of the nucleus stained by the basic dyes was given the name chromatin by Flemming.
Four classical cell-biology discoveries that NEET matches repeatedly: (1) ROBERT BROWN — first described the NUCLEUS as a cell organelle in 1831. (2) FLEMMING — named the material of the nucleus that stained with basic dyes CHROMATIN. (3) GEORGE PALADE — discovered RIBOSOMES (the protein-synthesis particles) using electron microscopy. (4) CAMILLO GOLGI — discovered the GOLGI APPARATUS, characterised by DISC-SHAPED SACS near the nucleus. These four constitute a NEET-favourite matching set. Memorise the year (Brown 1831), the staining method (Flemming used basic dyes to reveal chromatin), and the organelle-scientist pairings — they appear in nearly every chapter test.
NEET 2024 matched all four: Fleming-Chromatin, Brown-Nucleus, Palade-Ribosomes, Golgi-Discs near nucleus. Common confusion: Fleming the cell biologist (chromatin) ≠ Alexander Fleming the microbiologist (penicillin) — different people, similar names. Brown described the nucleus 28 years BEFORE Darwin's Origin of Species (1859). Palade's electron microscopy work earned a Nobel (1974). Golgi's disc-shaped sacs are also called CISTERNAE (cisternae of Golgi apparatus). Don't swap Brown (nucleus) with Flemming (chromatin) — both are nuclear discoveries, easy to confuse.
Robert Brown discovered chromatin and Flemming first described the nucleus as a cell organelle.
Robert Brown (1831) first described the NUCLEUS. Flemming named the basic-dye-staining material of the nucleus as CHROMATIN (later, after Brown).
Brown = nucleus (1831, FIRST). Flemming = chromatin (named the dye-staining material). Palade = ribosomes. Golgi = disc-shaped sacs.
- Robert Brown (1831) — first described the NUCLEUS as a cell organelle.
