Brightly coloured scented flowers generally show

A particular flower is brightly coloured and secrete nectar. The flower also secrete certain smell to attract insects. What can be inferred about its mode of pollination?

Read the following features Colourful, Nectarless, Fragrant, Ribbon like pollen, Feathery stigma How many of the given features are correct for bee pollinated flowers?

Read the following statements and find the suitable option a. Generally petals are green, leaf like and protect the flower in the bud stage b. Sepals are brightly coloured to attract insects for pollination c. If stamens in a flower remain free this is called polyandrous d. Each ovary bears one or more ovules attached to a flattened, cushion like placenta e. There may be a variation in the length of filaments of stamen with on flower, as in Salvinia and mustard.

Floral adaptations for entomphily: 1. Flowers are large and attractive. When small, they are clustered into an inflorescence (e.g. sunflower) 2. Flowers are brightly coloured, with pleasant fragrance. 3. Production of nectar which serves as food for the insects. 4. Additional modifications for attraction of insects, such as corona in passion flower and petalloid bracts iln Bougainvillea. 5. Pollen grains spiny and sticky for eash adherence to the stigma. Stigma is sticky. 6. Development of special mechanism such as lever mechanism in Salvia to favour insect pollination.
