Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Insects carry pollen from one plant to another. What else carries pollen?
A
wind
B
sun
C
petals
D
roots
Explanation: 

Detailed explanation-1: -This movement of pollen may occur by wind, as in conifers, or via symbiotic relationships with various animals (e.g., bees and certain birds and bats) that carry pollen from plant to plant while feeding on nectar.

Detailed explanation-2: -How does pollen get from one flower to another? 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”.

Detailed explanation-3: -Male part of the flowers (anther and filament-which together are called the ‘stamen’) are designed to expose pollen to the wind so that pollen can easily be blown by air currents. How? The filaments are often long (or at least dangly), with anthers dangling on the end, thus exposing the pollen to the air currents.

Detailed explanation-4: -Anemophilous, or wind pollinated flowers, are usually small and inconspicuous, and do not possess a scent or produce nectar. The anthers may produce a large number of pollen grains, while the stamens are generally long and protrude out of flower.

Detailed explanation-5: -Anemophily is the process when pollen is transported by air currents from one individual plant to another. About 12% of the world’s flowering plants are wind-pollinated, including grasses and cereal crops, many trees, and the infamous allergenic ragweeds.
