Question

Analyse the following pairs and identify the correct option given.
I. Chromoplasts   – Contain pigments other than chlorophyll 
II. Leucoplasts     – Devoid of any pigments
III. Amyloplasts  – Store proteins

V. Elaioplasts      – Store carbohydrates

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Cell Biology - Plastids
	**Related Topics**: Chloroplasts, Pigments, Storage
	**Prerequisites**: Basic understanding of plant cell organelles.
## SOLUTION PATHWAY
**Given Information**:
	Pairs of plastid types and their functions.
**Method & Steps**:
	1. **Analyze each statement individually:**
		Reasoning: Determine the veracity of each statement based on the function of each plastid.
	2. **Identify correct statements:**
		Working: Match the correct statements with the given options.
	3. **Select the correct option:**
		Result: Option A (I and II)
		Verification: Statements I and II are accurate descriptions of Chromoplasts and Leucoplasts, respectively.
## OPTION ANALYSIS
[A] ✓: **Correct**. Chromoplasts do contain pigments other than chlorophyll (like carotenoids), giving fruits and flowers their colors. Leucoplasts are colorless plastids lacking pigments; they store various substances.
[B] :x: **Incorrect**. While I and II are correct, III is incorrect. Amyloplasts store starch (a carbohydrate), not proteins.
[C] :x: **Incorrect**. II is correct (Leucoplasts are devoid of pigments). However, III is incorrect (Amyloplasts store starch), and while IV is correct (Aleuroplasts store oils and fats), the combination is not entirely accurate.
[D] :x: **Incorrect**. III, IV, and V are all incorrect. Amyloplasts store starch, not proteins. Aleuroplasts store oils and fats, not carbohydrates. Elaioplasts store oils and fats, not carbohydrates.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the storage function of different plastids: Ensure accurate memorization of the specific storage function of each plastid type (Amyloplasts - starch, Aleuroplasts - oils and fats, Elaioplasts - oils and fats, Proteinoplasts - proteins).
		2. Misinterpreting pigment presence/absence: Remember that chromoplasts have pigments other than chlorophyll, while leucoplasts lack any pigments.
	**Quick Tips**:
		1. **Mnemonic for storage plastids:**  **A**myloplasts - **A** (for starch/Amylose), **E**laioplasts & **A**leuroplasts - **EA** (Eat Avocados - oils and fats).
		2. **Color association:** Chromoplasts - **Chroma** (color), Leucoplasts - **Leuco** (white/colorless).
