Chromoplasts: The chromoplasts are the colored plastids. Chloroplasts are responsible for the characteristic color of flower and fruit. They contain yellow, orange and or red pigments.

Chromoplasts synthesize and store pigments such as orange carotene, yellow xanthophylls, and various other red pigments. As such, their color varies depending on what pigment they contain.

Types of Plastids

• Chloroplasts.
• Chromoplasts.
• Gerontoplasts.
• Leucoplasts.

chloroplast

The chlorophyll molecule consists of a central magnesium atom surrounded by a nitrogen-containing structure called a porphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as a phytol chain.

transparency or semitransparency. high tinting strength. mass tones that create intense tints when mixed with white (causing them to stay high key unless a complement is added, and creating less-natural light effects) warm-to-cool shift within a family.

Pigments are finely ground natural or synthetic, insoluble particles used to impart color when added to paints and coatings formulations. They are also used to impart bulk or a desired physical and chemical property to the wet or dry film. Some of the main pigment classes include: Organic pigments. Inorganic pigments.

Major plant pigments and their occurrence

Based on the method of their formulation, pigments can be categorized into two types: inorganic pigments and organic pigments.

Photosynthesis uses the light energy absorbed by chlorophylls to synthesize carbohydrates. All organisms on earth depend upon photosynthesis for food, either directly or indirectly. Chemists have identified more than 1,000 different, naturally occurring chlorophylls.
