The plastid that stores xanthophyll is known as ________.
Plastid Storage of Xanthophyll
Plastids are key organelles in plant cells responsible for pigment synthesis and storage. Different types of plastids specialize in storing specific substances.
Understanding Plastid Functions
- Chloroplasts: Primarily store chlorophyll, the green pigment essential for photosynthesis.
- Amyloplasts: Store starch granules.
- Chromoplasts: Store carotenoid pigments, including carotenes (orange) and xanthophylls (yellow). They are responsible for the colors of many flowers, fruits, and roots.
- Aleuroplasts: Store proteins.
Identifying the Xanthophyll Storage Plastid
The question asks which plastid stores xanthophyll. Xanthophyll is a yellow pigment belonging to the carotenoid family.
Based on their functions:
- Chromoplasts are specifically known to contain and store carotenoids like xanthophyll.
Therefore, the plastid that stores xanthophyll is the chromoplast.
Correct Answer: chromoplast
