Question

Which plastid imparts colour to flower petals?

Answer 1

Dear Student,

● Answer -

Chromoplast imparts color to flower petals.

◆ Plastids -

• Plastids are the double wall cell organelles found in cytoplasm of plants/organisms.

● Classification -

Plastids are classified as -

• Etioplast - it is precursor of chlorophyll

• Chromoplast - helps pigment synthesis

• Chloroplast - helps photosynthesis

• Leucoplast - synthesis of fatty acids

• Elaioplast - stores lipids
• Amyloplast - stores carbohydrates
• Proteinoplast - stores proteins

Thanks dear. Hope this is helpful to you..

Answer 2

PLASTIDS:

• Plastids that color flower petals are chromoplasts.
• Plastids are the cell organelles present exclusively in plant cells that contain several pigments that are used mainly for photosynthesis or coloring different parts of a plant.
• These plastids are of three types – chloroplasts, chromoplasts, and leucoplasts.
• Chloroplasts contain chlorophyll that performs photosynthesis.
• Chromoplasts contain carotenoids and xanthophylls that are responsible for all the red and blue colors of the plant parts like leaves and flowers.
• Leukoplasts have no pigment and they store starch in potatoes etc.
