Question

Water soluble pigment is present in cell vacuole is
A.Anthocyanin
B.Carotene
C.Xanthophyll
D.Chlorophyll

Answer 1

Hint: 1.Cell vacuole is a membrane bound organelle of the cell.
2.It is found in both plant and animals cells and in some fungi protists and bacterial cells.

Complete answer:
Cell vacuoles are filled with water containing organic and inorganic molecules. There can be the presence of pigments in the vacuole. Let us analyze the options to find out the correct answer.

Option A: Anthocyanins are water soluble vacuolar pigments which can appear red, purple, blue or black depending upon their pH. Plants rich in anthocyanin include raspberry, blueberry, black rice and black soybean. They belong to the class of flavonoids molecules and are odourless and moderately astringent. They are usually found in cell vacuole of a cell. Therefore, this is the correct option.

Option B: Carotene are photosynthetic pigments which are important for the process of photosynthesis. It contains no oxygen atoms and they absorb ultraviolet, violet and blue lights and scatter yellow, red or orange lights. It is found in chromoplasts of the plants. Therefore, this is the incorrect option.

Option C: Xanthophyll is a yellow color pigment. They are oxygen containing pigments which give color to fruits, flowers, vegetables, egg yolk, etc. Therefore, this is the incorrect option.

Option D: Chlorophyll are green color pigments found in leaves of the plants which help the leaves in the process of photosynthesis. They allow the plant to absorb energy from the light during photosynthesis. Therefore, this is the incorrect option.

Hence, the correct answer is option (A)

Note: Anthocyanins are used to color foods and beverages in the European countries. However, they are still not used as additives in food as their safety as food additives has yet not been verified.
