Question

Match List - I with List - II. 

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.

• A. (ii) (iii) (iv) (i)
• B. (iv) (iii) (ii) (i)
• C. (i) (iv) (iii) (ii)
• D. (iii) (iv) (i) (ii)

Answer 1

The Correct Option is D

To solve the question, we need to match the terms in List - I with their correct descriptions in List - II:

1. Cristae: These are infoldings in the mitochondria. They increase the surface area available for biochemical reactions, particularly those involved in cellular respiration. Thus, it matches with (iii).
2. Thylakoids: These are flattened membranous sacs located in the stroma of plastids and are involved in the photosynthesis process. They are structures within chloroplasts. Thus, they match with (iv).
3. Centromere: This is the primary constriction region in a chromosome, crucial for the proper segregation of chromosomes during cell division. Therefore, it matches with (i).
4. Cisternae: These are disc-shaped sacs frequently found in a Golgi apparatus. They assist in modifying and packaging proteins. Hence, they match with (ii).

Thus, the correct matching is:

• (a) Cristae - (iii) Infoldings in mitochondria
• (b) Thylakoids - (iv) Flattened membranous sacs in the stroma of plastids
• (c) Centromere - (i) Primary constriction in chromosome
• (d) Cisternae - (ii) Disc-shaped sacs in Golgi apparatus

Therefore, the correct answer is (iii) (iv) (i) (ii).
