It depends on the plant. Many plants simply release their pollen to the wind, like grasses and conifer trees. Some plants have flowers to attract various animals that carry pollen from flower to flower and pollinate them that way.
Most grasses and many trees are pollinated by the wind. The pollen carrying organs of these types of plant are exposed so that the wind can distribute their pollen, catkins are a typical wind pollinated structure. Insect pollinated plants need to attract insects to their flowers and they generally have petals and are often brightly coloured.
The pride o barbados is insect pollinated because it produces sweet nectar and is brightly coloured which attracts insects.
A plant with a sticky stigma is more likely to be insect-pollinated. The stickiness of the stigma helps to capture pollen grains brought by insects. Wind-pollinated plants typically have feathery stigmas to catch pollen grains carried by the wind.
Sampaguita is primarily cross-pollinated, where the transfer of pollen occurs between different flowers by insects like bees. In some cases, self-pollination can also occur within the same flower when the pollen is transferred from the anther to the stigma.
Holly bushes are typically pollinated by wind, as they have separate male and female plants where wind helps to carry pollen from male flowers to female flowers. Once pollinated, female flowers will develop into the red berry-like fruits that are characteristic of holly bushes.
Insects and wind.
grasses
Because they are pollinated by wind.
Grasses and grains are wind-pollinated, and plants are seed pollinated. There is a difference.
Common examples of anemophilous (wind-pollinated) plants are ragweed, grass, and conifers.(Generally, any pollen that is considered an allergen, comes from an anemophilous plant)
That is a matter of taste. Grasses (the prime example) can be very attractive. It is the flower not the plants being attractive in case of insect pollinated and not so attractive in case of wind pollinated.
No. Corn is really a variety of grass, and grasses are wind pollinated.
Because they are wind pollinated so they have no need to attract insects.
Grasses belong to the family of Poacaea (formerly Graminae) and are plants with sheathing leaves, and generally bear their seeds on a particular stalk. Mostly wind pollinated. Bamboo and sugar cane are among the larger grasses.
Wind-pollinated plants are primarily responsible for causing more hay fever than insect-pollinated plants. This is because wind-pollinated species, such as grasses, trees, and some weeds, release large quantities of lightweight pollen into the air, which can easily be inhaled by people. In contrast, insect-pollinated plants tend to produce heavier, stickier pollen that is less likely to become airborne and cause allergic reactions. Therefore, individuals with hay fever are more affected by pollen from wind-pollinated plants.
They don't need to be. Color is one method used by insect pollinated plants to attract the insects. Wind pollinated plants such as Grasses and Pine trees don't need to attract pollinators. The male flowers simply release the pollen on to the breeze on a "hit or miss" basis.
because, they are mainly wind pollinated and don't require bright flowers to attract insects
