(2)chromoplast
(3)aleuroplast
(4)amyloplast

✓

Verified Against NTA Final Answer Key

Option (2) : chromoplast

📚 Cell: The Unit of Life Easy

📋 Given Parameters & Problem Setup

Pigment Stored Xanthophyll (yellow fat-soluble carotenoid pigment)

Target Organelle Type of plastid that stores xanthophyll

⚡

The 30-Second Exam Hall Shortcut: ⚡ Chroma = Color (Yellow, Orange, Red)

⏱️ Save ~40 seconds

Chromoplasts store fat-soluble carotene & xanthophyll pigments to give flowers/fruits vibrant color!

1 Recall plastid classification based on pigments: Chloroplasts, Chromoplasts, and Leucoplasts.

2 Chloroplasts store chlorophyll (green).

3 Leucoplasts are colourless and store starch (amyloplast), oil (elaioplast), or protein (aleuroplast).

4 Chromoplasts store fat-soluble carotenoids: carotene and XANTHOPHYLL (yellow-orange-red).

5 Option (2) is Chromoplast! Pick Option (2) in 5 seconds!

🛡️

Why You Can 100% Trust This Shortcut: NCERT Cell Biology verbatim: In chromoplasts fat soluble carotenoid pigments like carotene, xanthophylls and others are present.

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Classify Plastids Based on Pigment Content

Plastids are found in all plant cells and euglenoids. Based on the presence or absence of specific pigments, Schimper classified plastids into three types: 1. Chloroplasts: Contain chlorophyll and carotenoid pigments for photosynthesis. 2. Chromoplasts: Contain fat-soluble carotenoid pigments such as carotene and xanthophylls, imparting yellow, orange, or red color to petals, pericarp, and ripening fruits. 3. Leucoplasts: Colourless plastids of varied shapes and sizes that store nutrients.

\text{Chromoplast} \equiv \text{Plastid containing Carotene and Xanthophyll}

• Xanthophyll is an oxygenated carotenoid (yellow pigment).

Step 2

Evaluate the Sub-types of Leucoplasts

Leucoplasts store reserve foods and do NOT store pigments: - Amyloplasts: Store carbohydrates (starch, e.g., potato tuber). - Elaioplasts: Store oils and fats. - Aleuroplasts: Store proteins (aleurone grains).

\text{Amyloplast: Starch}; \quad \text{Aleuroplast: Protein}; \quad \text{Elaioplast: Fat}

• Amyloplast and aleuroplast are non-pigmented nutrient storage plastids.

Step 3

Conclusion

The plastid that stores xanthophyll is known as chromoplast.

\text{Matches Option (2)}

4-Option Deep Scan

1 A

✗ Incorrect

Verdict & Scientific Reason:

Incorrect. While chloroplasts have accessory carotenoids, the specialized plastid dedicated to storing high concentrations of xanthophylls and carotenes to color plant organs is the chromoplast.

⚠️

Student Fallacy (Why candidates pick this trap): Assuming all plant pigments are stored in chloroplasts.

2 B

✓ 100% Correct

Verdict & Scientific Reason:

Exact match with NCERT definition of chromoplasts as repositories for fat-soluble carotene and xanthophyll pigments.

💡

Why this is airtight: None; textbook precision.

3 C

✗ Incorrect

Verdict & Scientific Reason:

Incorrect. Aleuroplasts are colourless leucoplasts that store proteins.

⚠️

Student Fallacy (Why candidates pick this trap): Confusing protein-storing aleuroplast with pigment-bearing plastid.

4 D

✗ Incorrect

Verdict & Scientific Reason:

Incorrect. Amyloplasts store carbohydrates/starch.

⚠️

Student Fallacy (Why candidates pick this trap): Confusing starch storage with xanthophyll storage.

⚠️

NTA Trap Alert: Confusing Leucoplast Storage Types with Chromoplasts

Students frequently memorize amyloplast (starch), elaioplast (oil), and aleuroplast (protein), and panic when asked about xanthophyll. Xanthophyll is a PIGMENT, so it belongs to CHROMOPLAST (chromo = color)!

🛡️ How to avoid the -1 mark: Chromo means color. Xanthophyll is yellow pigment, so it resides in Chromoplast.
