Question

Match List-I with List-II

List-I (Cell organelles)	List-II (Functions)
(A) Ribosomes	(I) Contains waste materials and water
(B) Golgi bodies	(IV) Formation of cell wall
(C) Chromoplasts	(II) Contains carotenoid pigment
(D) Vacuole	(III) Protein synthesis

• A. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
• B. (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
• C. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
• D. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Hint:

- Ribosomes \(\rightarrow\) The "protein factories" of the cell.
- Vacuole \(\rightarrow\) Regulates cell turgor and acts as a storage tank.
- Chromoplasts \(\rightarrow\) Pigment-rich plastids (excluding green chlorophyll, which is in chloroplasts).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Plant cells contain various membrane-bound and non-membrane-bound sub-cellular structures called organelles, each specialized to perform specific metabolic, synthetic, or storage functions within the cell.

Step 2: Detailed Explanation:
Let us match each cell organelle with its primary biological function:
- (A) Ribosomes:
Ribosomes are molecular machines composed of ribosomal RNA and proteins.
They serve as the site of translation, where genetic codes carried by mRNA are translated into polypeptide chains during protein synthesis.
Thus, (A) matches with (III).
- (B) Golgi bodies (Golgi apparatus):
In plant cells, the Golgi apparatus (often referred to as dictyosomes) is highly involved in synthesizing and secreting non-cellulosic cell wall polysaccharides like hemicellulose and pectin, which are transported in vesicles to the growing cell plate during cytokinesis.
Thus, (B) matches with (IV).
- (C) Chromoplasts:
Chromoplasts are plastids containing high concentrations of carotenoid pigments (yellow, orange, and red), giving distinct colors to flowers, fruits, and aging leaves to attract pollinators.
Thus, (C) matches with (II).
- (D) Vacuole:
The central vacuole in mature plant cells is a large membrane-bound organelle (enclosed by the tonoplast) that stores water, cell sap, inorganic ions, organic acids, and cellular waste materials, maintaining turgidity.
Thus, (D) matches with (I).
Combining these matches, we get: (A)-(III), (B)-(IV), (C)-(II), (D)-(I).

Step 3: Final Answer:
The correct matching sequence corresponds to Option A.
