Observe the given diagram and answer the questions given below:
Match List I with List II
| LIST I | LIST II |
|---|---|
| A. Nucellus | I. G |
| B. Megaspore dyad | II. B |
| C. Micropylar end | III. D |
| D. Megaspore mother cell | IV. C |
Choose the correct answer from the options given below.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-IV, B-III, C-I, D-II
(A) Nucellus — this matches (IV) C. C points to the tissue of the ovule that surrounds the dividing cells; this mass of cells is the nucellus.
(B) Megaspore dyad — this matches (III) D. In the second drawing the large cell has divided once (meiosis I) into two cells, the dyad.
(C) Micropylar end — this matches (I) G. G marks the end of the ovule near which the megaspore mother cell forms; the cells of the tetrad lie in a row from this end towards F.
(D) Megaspore mother cell — this matches (II) B. B in the first drawing is the single large cell with dense cytoplasm and a prominent nucleus, before any division.
