AP BIOLOGY

Detailed explanation-1: -Scent can also attract insects and birds which then carry the pollens. The sweet scent is very alluring for the insects and hence we often observe a lot of insects on the flowers that smell sweet. The insects come in search of nectar and in return they carry the pollen grains that get stuck with their bodies.

Detailed explanation-2: -To differentiate itself from other flowers, each species’ flowers puts out a unique scent to attract specific pollinators. Similar to the perfumes at a department store counter, flower scents are made up from a large and diverse number of chemicals which evaporate easily and float through the air.

Detailed explanation-3: -Some flowers use scent to attract pollinators. Scent is a signal that helps pollinators find and select particular flowers. These floral scents are typically a complex mixture of highly volatile compounds and essential oils that flowers emit into the atmosphere.

Detailed explanation-4: -By providing species-specific signals, flower fragrances facilitate an insect’s ability to learn particular food sources, thereby increasing its foraging efficiency. At the same time, successful pollen transfer (and thus, sexual reproduction) is ensured, which is beneficial to plants.

Detailed explanation-5: -Corolla consists of petals which are the coloured part of the flower and attract the insects for pollination.
