Which of the following pairs of plastids and the substances they store is NOT correct?[SSC CPO 10/11/2022 (Evening)]

Statements:
I. Chloroplasts – Store starch
II. Chromoplasts – Store pigments
III. Leucoplasts – Store proteins, starch, and oils
Detailed Solution for Test: SSC CGL Previous Year Questions: Biology (2023-20) - 1 - Question 20

  1. Chloroplasts – Store starch (Incorrect)
    Chloroplasts are primarily involved in photosynthesis, producing glucose, which is later stored as starch in other organelles like amyloplasts (a type of leucoplast). Hence, saying that chloroplasts "store" starch is incorrect.

  2. Chromoplasts – Store pigments (Correct)
    Chromoplasts contain pigments like carotenoids (yellow, orange, and red pigments) that give color to fruits, flowers, and aging leaves.

  3. Leucoplasts – Store proteins, starch, and oils (Correct)
    Leucoplasts are colorless plastids responsible for the storage of different substances:

    • Amyloplasts store starch.

    • Elaioplasts store oils and fats.

    • Proteinoplasts store proteins.

Since Statement I is incorrect, while Statements II and III are correct, the correct answer is "Only I"
