What is a pollen vector?
Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.
How is pollen transferred?
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 can’t move on its own, so animals or the wind (and water in rare cases) move the pollen for plants.
Do all flowers have pollen?
Many flowers, shrubs, trees, and grasses make very little or even no pollen. And some species produce it only in certain plants. For those, all you need to do is to make sure you have female plants — the ones that don’t make the sneezy, yellow stuff.

How do butterfly sips nectar?
Butterflies eat by extending the proboscis deep into a flower to sip nectar. Butterflies also use the proboscis to drink water and juice from rotting fruits. The butterfly reaches all the way to the bottom of the trumpet-shaped flower to find the nectar at the very bottom.
What plants have a lot of pollen?
Plants that give off the most pollen include:
- Trees like oak, ash, elm, birch, maple, alder, and hazel, as well as hickory, pecan, and box and mountain cedar.
- Grasses like Timothy, Kentucky blue grass, Johnson, Bermuda, redtop, orchard grass, sweet vernal, perennial rye, salt grass, velvet, and fescue.
What makes a flower a vector for pollen?
Animals, wind, and water can all be vectors for pollen. The flower type, shape, color, odor, nectar, and structure vary by the type of pollinator that visits them.
Which is the primary pollination vector for bees?
‘Bees occasionally collect olive pollen, but wind is the primary pollination vector.’ ‘In addition to seeds, the promoters directed reporter gene expression in pollen and in seed coats.’ ‘Pollen traps also indicate that pollen is shed directly into the air, permitting wind pollination.’
What do you call the transfer of pollen from one plant to another?
When the transfer of pollen occurs between one plant’s anther and another plant’s stigma of the same species, it is called cross pollination. When the transfer occurs from the anther to the stigma of either the same or another flower borne on the same plant it is called self pollination. Pollen grains travel via either biotic or abiotic vectors.
What do you call an animal that collects pollen?
We call animals or insects that transfer pollen from plant to plant “pollinators”. Pollination is usually the unintended consequence of an animal’s activity on a flower. The pollinator is often eating or collecting pollen for its protein and other nutritional characteristics or it is sipping nectar from the flower when pollen grains attach
