Wind or insect pollination?
Teaching notes and answers
Our staple foods e.g. wheat and rice are wind pollinated. If we lost a large number of
insect pollinators we would still have plenty to eat but we would lose foods which
provide us with essential micro-nutrients, vitamins and minerals, antioxidants and
variety in our diet.
Although insect pollinated, most potatoes are reproduced asexually, from tubers.
Many fruits such as citrus fruits, bananas, figs, kiwi, coconuts can be self pollinated but
they produce more fruit if they are pollinated by insects.
Vegetables are largely insect pollinated.
