Solution
The correct option is D Nectar and pollen grains
Flowering plants need to get pollen from one flower to another, either within a plant for self-pollination or between plants of the same species for cross-pollination to occur. However, pollen cant move on its own, so animals or the wind (and water in rare cases) move the pollen for plants.Many flowers use colours to attract insects, sometimes helped by coloured guiding marks. Some have ultraviolet marks that can be seen by insects but are invisible to human eyes. Flowers are often shaped to provide a landing platform for visiting insects or to force them to brush against anthers and stigmas.Some flowers have scent to attract insects. Many of these scents are pleasing to humans too, but not all some flowers attract flies with a smell of rotting meat. Colours cant be seen in the dark, so scent is important for flowers that are pollinated by night-flying insects such as moths. Most bird-pollinated flowers have lots of nectar, often at the bottom of a tube of petals. Birds need to brush against anthers and stigmas when reaching for the sugary reward with their long beaks. Some birds, such as t, stitchbirds and bellbirds, have special brush-like tips to their tongues to help them soak up the nectar.
