Pollination
A discussion of how plants attract insects, and insects find flowers from which they extract nectar and pollen - both food sources - and pollinate the plant in the process.
Since plants have to mate and produce offspring while rooted to the spot, they have to be pollinated – by wind, water, or animals – most commonly insects. They use a surprising array of tricks to attract pollinators: striking colours, iridescent light effects, and enticing scents, to name but a few.
Insects, on the other hand, do not seek to pollinate plants – they are looking for food; so plants make sure it’s worth their while. Insects are also remarkably sophisticated in their ability to find, recognise and find their way inside flowers.
So pollination has evolved as a complex dance between plants and pollinators that is essential for life on earth to continue.
