Qns 61 to 65 Read the passage given and answer the questions that follow.
The colours you see in flowers come from the DNA of a plant. Genes in a plant’s DNA direct
cells to produce pigments of various colours. When the flower is red, it means that the cells in
the petals have produced a pigment that absorbs all colours but red. When you look at that
flower, it reflects red light. So, the flower appears to be red. Flowers are the reproductive
parts of plants. They attract insects to pick up pollen and transfer it to other plants and
flowers. This helps the plant to reproduce. Some flowers change colour or fade over time. This
is an indication to the pollinators that pollination is no longer needed. Many of the actual
chemicals in the petals of a flower are called anthocyanins. These are water soluble
compounds that belong to a bigger class of chemicals called flavonoids. Anthocyanins are
responsible for creating blue, red, pink, pink and purple colours in flowers. Other pigments
that produce floral colours include carotene (for red and yellow), chlorophyll (for green in
petals and leaves) and xanthophyll (a pigment that produces yellow colours).
