Over millions of years, flowers have developed scents, colors, markings and shapes to attract certain pollinators, and certain pollinators have developed characteristics such as long tongues or beaks that enable them to reach the nectar in differently shaped flowers.
How are petals used for pollination?
For example, large petals and flowers will attract pollinators at a large distance or that are large themselves. Collectively the scent, color, and shape of petals all play a role in attracting/repelling specific pollinators and providing suitable conditions for pollinating.
How is the insect pollinated flower adapted for its function?
The flowers pollinated by insects are bright-coloured and produce nectar. The fragrance of the flowers attracts the insects. The pollen is sticky, large, heavy and rough so that stick to the body of the insects. The stigmas are also sticky so that the pollens depositing are not dispersed.
What are the features of insect pollinated flowers?
- Insect-pollinated flowers are large, have brightly colored petals, are often sweetly scented, usually contain nectar- to attract insects.
- Its pollen are often sticky or spiky – to stick to the legs and body of insects.

Which layer of the flower can attract insects?
Corolla is the outermost layer of the flower and are brightly coloured which helps attract insects to them which in turn help in the process of pollination.
What part of the flower is the most attractive where it uses to attract insects?
Petals are what give a flower its unique shape, and are often brightly colored to attract insects and critters, which unwittingly aid in the fertilization of ovules through pollination.
What are some adaptations of flowers?
Plants have some interesting adaptations that help them. Flowers are an adaptation that helps many plants make seeds to grow new plants. Some flowering plants use bright petals and sugar water called nectar to get insects to visit. Visiting insects help move pollen among flowers so seeds will form.
How are the male parts of wind pollinated flowers adapted to their functions?
The anthers are large and they grow at the tip of the long, flexible filaments. This exposes them to the wind and makes it easy for the pollen to be carried away, even by just a light breeze. For pollination to take place, the pollen must reach the female flower organs: the carpel.
How is lily flower adapted for pollination?
Their bright colors call in butterflies and bees, the lily’s primary pollination assistants. Insect helpers jump from flower to flower, carrying pollen from the stamens to the pistils. Pollen attaches to the sticky stigma and then works its way down the style and into the ovary.

What structural modifications are found in insect pollinated flowers?
Answer: The structural modifications that are found in insect pollinated flowers are: a) The petals of these flowers are large, conspicuous and contain pigments like xanthophyll, anthocyanin, carotene, that make these petals brightly coloured. Bright coloured petals attract insect towards it.
Why do flowers pollinated by insects have large bright petals?
In order to attract insects, insect-pollinated flowers are often brightly coloured, have scent and nectar so that the insect comes into the flower and collects or leaves pollen.
Why are insect-pollinated flowers more attractive?
Insect-pollinated flowers are expected to be more attractive because petals of insect-pollinated flowers are scented and coloured. Wind-pollinated flowers have very small petals or no petals at all. This is because they are pollinated by wind and not by insects.
Are petals insect-pollinated or wind-pollinated?

How are insect-pollinated flowers are different from wind pollinated flowers?
In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily. In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains.
Do wind pollinated flowers have petals?
Wind-pollinated flowers are typically: No bright colors, special odors, or nectar. Small. Most have no petals.
Why do flowers pollinated by wind have little Colour no petals or sent?
Wind and water pollinated flowers are light in weight as air and water cannot carry heavy pollens. They are neither colorful nor nectar producing as these are the characters for the insect-pollinated flowers.
Why do petals of flowers differ from plant to plant?
Explanation: Petals are essentially modified leaves. Plants have different leaf patterns depending on their strategy for moisture conservation and use of sunlight for photosynthesis. Petal size and variety will depend on the plant’s strategy for pollination.
What is the function of the petals?
Petals (collectively called the corolla) are also sterile floral parts that usually function as visually conspicuous elements serving to attract specific pollinators to the flower.
