Pollination is the process of transferring pollen from anthers to the stigma of a flower. Features of insect-pollinated flower: Flowers are brightly coloured, scented and secrete nectar. Sepal-Sepals are modified leaves which enclose and protect the other parts of the flower in the bud stage.-The sepals combine to form the calyx.-Some flowers have another layer of floral leaves outside the sepal which make up the epicalyx of the flower. structure also evolved in a monocotyledonous group of insect pollinated plants: the orchids. light,feathery.

They may have traps to keep the beetle longer. In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily. The flower should be colorful. Some butterflies are able to see red as a distinct color, so some butterfly-pollinated flowers are red and orange. The pollen grains of anemophilous species are smaller and lighter than those of insect-pollinated flowers. The insects come to the plant for their sweet nectar, and in the process, they carry the pollen to other plants, and this lets the plants reproduce. The petals of an insect-pollinated flower are bright and colored to attract insects. Orchids display an amazingly diverse array of flowers. has a sticky stigma. 0.

Pollinators visit flowers in their search for food (nectar and pollen). One well-studied example of a moth-pollinated plant is the yucca plant, which is pollinated by the yucca moth. In wind-pollinated species, the microsporangia hang out of the flower, and, as the wind blows, the lightweight pollen is carried with it. bats) to transfer the pollen grains from the anther of one flower to the stigma of another flower. These are the flower's reproductive organs involved in pollination. The insects are attracted by the colour and scent of the flowers.
