Yes, insects are needed to pollinate some flowers but no, they are not needed to pollinate all flowers. Insects count -- along with bats, birds, and some mammals and reptiles -- among nature's pollinators.
There will be no flowers and fruits.
Flowers on vines can be pollinated by a variety of insects, such as bees, butterflies, and moths. These insects may visit the flowers to collect nectar or pollen, inadvertently transferring pollen between flowers as they move. Some vine flowers are also capable of self-pollination if pollinators are scarce.
Yes, monarch butterflies can indirectly help pollinate flowers as they visit them for nectar. While they are not as efficient as bees or other insects, their movements between flowers can help transfer pollen and facilitate pollination.
Nettles are wind-pollinated plants. Their tiny, inconspicuous flowers produce abundant pollen that is carried by the wind to other flowers for pollination. Nettles do not rely on insects or other animals for pollination.
Tobacco flowers that need moths to pollinate have evolved to have white flowers. Tobacco flowers that need hummingbirds to pollinate have evolved to be deep pink.
In short, they do. Greenhouses are not usually sealed, and insects can get in and out, and they will pollinate the flowers.
yes
To attract insects to pollinate the plants.

No. There are plenty of other insects which pollinate flowers.
Flowers smell to attract the insects that pollinate them.
You let the insects pollinate the flowers, then you grab the flowers and feed the plant to the animal.
Flowers attract insects. Insects pollinate the flowers. Pollinated flowers produce seeds. Seeds grow into apples.
Because these colours attract insects and the flowers need the insects to pollinate them. Hope this helps!
Flies and all other insects that fly from flower to flower will help to pollinate.
yes flowers need particular insects to pollinate them.
