Yes Anthocyanin pigment is present in vacuoles which is responsible for colouration of petals.

Water soluble pigments found in plant cell vacuoles are anthocyanins.

Anthocyanins are a group of water-soluble pigments responsible for the red, purple, and blue colors in many fruits, flowers, and leaves. They are widely distributed in the plant kingdom and are particularly abundant in the vacuoles of plant cells.

Key Points:
- Anthocyanins are water-soluble pigments found in plant cell vacuoles.
- They are responsible for the red, purple, and blue colors in fruits, flowers, and leaves.
- Anthocyanins are widely distributed in the plant kingdom.

Explanation:

- Water-soluble pigments: Anthocyanins are water-soluble pigments, meaning they can dissolve in water. This characteristic allows them to be stored in the vacuoles of plant cells, which are filled with water.
- Plant cell vacuoles: Vacuoles are membrane-bound organelles found in plant cells. They play a crucial role in storing various substances, including pigments. Anthocyanins are stored in the vacuoles of plant cells, where they can be easily accessed for various functions.
- Red, purple, and blue colors: Anthocyanins are responsible for the vibrant red, purple, and blue colors observed in many fruits, flowers, and leaves. These pigments absorb light in the green to yellow range and reflect light in the red, purple, and blue range, giving rise to these colorful hues.
- Widespread distribution: Anthocyanins are widely distributed in the plant kingdom. They can be found in a variety of plant species, including flowering plants, ferns, and mosses. Different plants produce different types and amounts of anthocyanins, leading to a wide range of colors in nature.

Overall, anthocyanins are important water-soluble pigments found in plant cell vacuoles. They contribute to the diverse colors seen in fruits, flowers, and leaves and are widely distributed throughout the plant kingdom.
