Question

Anthocyanin pigment occurs in
A. Chromoplasts
B. Amyloplasts
C. Cytoplasm
D. Cell sap

Answer 1

Hint: Anthocyanins are compounds that give color to several fruits and flowers like berries, grapes, etc. These are phenolic compounds with antioxidant properties. These are used as Natural dyes and food colors. Anthocyanins are water-soluble and are seen in the glycosylated form. The color of the pigment varies from red to purple shades. The variation in color depends upon the pH, temperature, and other physiological characters.

Complete answer:
Anthocyanins are produced in plant cells inside the vacuoles. Vacuoles are membrane-bound space in plant cells that occupy a large area of the plant cell cytoplasm. It is covered by a layer of tonoplast, which is a single membrane structure. Vacuole contains water, the cell sap, excretory materials which are unnecessary for the cell. Vacuoles are also seen in plants, protists, bacteria, etc.
All plant cells contain plastids that are large and contain several pigments that give a specific color to plant parts. Based on the differences in pigments plastids are classified into the chloroplast, chromoplast, and leucoplast. Chlorophyll and carotene pigments required for trapping light energy for photosynthesis is seen in the chloroplast. Fats soluble carotenoid pigments like carotene, xanthophyll is seen in chromoplast. They give yellow, red, orange colors to the plants. Amyloplasts are for the storage of carbohydrates.
Cytoplasm includes all the things seen inside a cell. It is bounded by the cell membrane. It is a semi-fluid matrix inside the cell which occupies the volume of the cell. It is the ground for various cell activities. Vacuoles and other cell organelles are seen in the cytoplasm. The cell sap is found inside the vacuole and anthocyanin is seen within the vacuole in the cell sap.

Therefore the correct answer is option (D), Cell sap.

Note: Anthocyanins are antioxidants that give color to different fruits and leaves. The color varies from red-blue to purple shades. The color providing fat-soluble pigments are usually seen in chromoplasts. But anthocyanins are water-soluble phenolic substances and are seen inside the vacuoles. Some fruits having anthocyanins are blueberries, grapes, raspberries, black rice, etc.
