No they don't, they usually don't have any coloured flowers because they don't need to attract birds or insects so pollination can take place and they don't have any nectar. hope this help :)
Maybe
wind and bees
Wind pollinated flowers usually have light seeds, with some kind of method for being carried on the wind, like helicopter seeds have big 'sails' which are blown over long distances in the wind
Grasses and grains are wind-pollinated, and plants are seed pollinated. There is a difference.
Silver Birch are wind pollinated.
yes
wind pollinated
There are more than 2 flowers which are not colorful and showy. All anemophilous flowers (Flowers which are pollinated by wind) are such flowers as they have no need to attract insects or birds for pollination. Examples for such flowers are : Grass species, Coniferous trees (Pine trees), Ragweed flowers, Hickory family, the Hoary Plantain and Sweet Chestnuts.
They are not better they are different.

Generally plants which present small, non-colorful flowers are wind pollinated. If you plant has flowers which give off an aroma, are colorful and or are large in size, they are more likely to rely on pollinators.
They are most likely pollinated by wind or pollinators, such as bees.
It's bright and showy, and even has little nectar ducts under its petals, so insect-pollinated. Wind-pollinated plants generally don't have flowers, or the flowers are very small and inconspicuous, like those of grass. Wind-pollinated plants also make far more pollen (try tapping a pine tree or reed in spring) because the wind does not take it directly to its destination, much of it will be lost. With insects there's a fair chance the little there is will reach another flower of the same species.

Lemon seed is not pollinated. The lemon tree has flowers, which are pollinated by insects and wind. The pollinated flowers grow into lemons, which contain seeds.
