Question

Water soluble pigment isa) Chlorophyll b)  Carotene c) Anthocyanin d)  Xanthophyll Correct answer is option 'C'. Can you explain this answer?

Answer

Yes anthocyanins

Answer

Anthocyanins are water soluble flavonoid pigment that appears red to blue according to pH.
So option ' C ' is correct answer.

Answer

Water soluble pigments is anthocyanin which is present in cell sap of vacuoles . It's function is to colour sepals nd petals of flowering plant .

Answer

Anthocyanins are water soluble strong colours and have been used to colour food since historical times. Extracts of berries have been used to colour drinks, pastries and other foods. Anthocyanins are water soluble, which restricts the use, and are pH dependent. When the acidity changes, the colour changes. For example, the colour of red cabbage is enhanced with the addition of vinegar or other acid. On the other hand, when cooked in aluminium pans, which cause a more alkaline environment, the colour changes to purple and blue.

Answer

Understanding Water Soluble Pigments
Water-soluble pigments are types of pigments that can dissolve in water, unlike their fat-soluble counterparts. Among the options provided, the correct answer is C) Anthocyanin.
Characteristics of Anthocyanin
- Water Solubility:
Anthocyanins are known for their ability to dissolve in water, which is a key characteristic that distinguishes them from other pigments like chlorophyll and carotenoids.
- Color Range:
These pigments are primarily responsible for the red, purple, and blue colors found in many fruits, vegetables, and flowers. Their color can change depending on pH levels.
- Biological Role:
Anthocyanins play a significant role in plant protection against UV radiation, pests, and diseases. They also attract pollinators and seed dispersers.
Comparison with Other Pigments
- Chlorophyll:
Primarily a green pigment, chlorophyll is fat-soluble and crucial for photosynthesis.
- Carotene:
Carotene is another fat-soluble pigment, responsible for orange and yellow colors, found in carrots and other vegetables.
- Xanthophyll:
Similar to carotene, xanthophyll is a fat-soluble pigment that primarily appears yellow and is involved in photosynthesis.
Conclusion
In summary, among the pigments listed, anthocyanins are the only water-soluble pigments, making option C the correct choice. Understanding the solubility and functions of various pigments is essential for studies in botany and agriculture, especially in the context of plant health and nutrition.
