Question

Bright colour of petals is due to the presence of(i) chloroplast (ii) leucoplast (iii) chromoplast (iv) none of these​

Answer 1

Answer:

it will be none of these

Explanation:

chloroplast produces chlorophyll.

chromoplasts produces carotene, a red - green pigment, which mostly gives colors to tomato like its green at first then becomes red.

leucoplasts are used to store starch, and proteins.

Then, there's a pigment called Anthocyanin which gives petals a bluish purple color, that is it gives color to the petals and 'tis found in the cell sap, so yeah all the given options are incorrect.

Answer 2

Bright colour of petals is due to the presence of anthocyanins.

• Chromoplasts are variously coloured plastids that are mostly present in petals of flowers and in fruits.
• The colouring substances associated with them are xanthophyll and carotene.
• Some colouring pigments such as anthocyanins are not associated with plastid. Instead, they remain dissolved in the cell sap.
• The corolla consists of a number of petals. In majority of flowers, petals are brightly coloured, scented, and are of various shapes.
• Chloroplast is a cell organelle in which the physiological process of photosynthesis takes place.
• Leucoplasts are colourless plastids. They have no pigment and they store starch.
