List-I | |
List-II |
| (a) | Cristae | (i) | Primary constriction in chromosome |
| (b) | Thylakoids | (ii) | Disc-shaped sacs in Golgi apparatus |
| (c) | Centromere | (iii) | Infoldings in mitochondria |
| (d) | Cisternae | (iv) | Flattened membranous sacs in the stroma of plastids |
Choose the correct answer from the options given below.
Correct Answer :
(a) : (iii) ; (b) : (iv) ; (c) : (i) ; d) : (ii))
Solution :
To find the correct match, let us analyze the biological structures listed in List-I and pair them with their corresponding descriptions in List-II:
(a) Cristae:
Cristae are the inner folds or infoldings of the inner mitochondrial membrane. They increase the surface area available for aerobic respiration and ATP synthesis.
Hence, (a) matches with (iii).
(b) Thylakoids:
Thylakoids are flattened, membranous sacs arranged in stacks (grana) within the stroma of plastids (such as chloroplasts). They contain photosynthetic pigments.
Hence, (b) matches with (iv).
(c) Centromere:
The centromere is the primary constriction region of a chromosome where the two sister chromatids are held together and to which the spindle fibers attach during cell division.
Hence, (c) matches with (i).
(d) Cisternae:
Cisternae are flattened, disc-shaped, membrane-bound sacs or vesicles stacked together to form the Golgi apparatus.
Hence, (d) matches with (ii).
Combining all the correct matches:
• (a) : (iii)
• (b) : (iv)
• (c) : (i)
• (d) : (ii)
