The answer is really pretty simple. Flowers that are pollinated by insects are pollinated by insects going from one flower to an other, carrying pollen from one flower to the next. Wind pollination is caused by the wind carrying pollen from one flower to an other one.
Usually insect pollinated flowers have large, brightly colored petals also sweet scented nectaries at the base of the petals - some flowers may look bland but when viewed under ultra violet or infrared light are very conspicuous.
The Stamen is short, with anthers firmly attached inside the flower. The Stigma is sticky and is located on the inside of the flower. Additionally the pollen grain are produced in small amounts, it is rough/ spiky and its large. This features are used to attract insects for pollination. The pollen grains are sticky and rough so it clings onto the insect's body. The Stigma is also sticky so the pollen grains remains in place and wont get carried away by the wind currents.
Many, but not all dicotyledonous flowers are insect pollinated.
Wind pollinated flowers are small and inconspicuous. Sometimes green or brown in color and has no scent or nectaries (such as the flowers of grass plants).
The Stamen has long filaments, with anthers that hang outside the flower. The Stigma is large, branched and feathery. The pollen grains are produced in large amounts, its smooth and light hence it can be carried away by the gentlest of wind currents.
Many, but not all monocotyledonous flowers and cone producing gymnosperms are wind pollinated.
Wind-pollinated plants produce small, lightweight pollen grains that are easily dispersed by air currents. These pollen grains are often smooth and non-sticky. In contrast, insect-pollinated plants produce larger, stickier pollen grains that can adhere to insects and be transported between flowers.
Insect pollinated is attractive and colourful, the former isn't
Besides petal color the insect pollinated flowers also have insect attracting smell where as in wind pollinated flowers the petals are neither attractive nor scented.
Insect pollination :
Is pollination helped by insect, usually the flower have bright color, and have a nectar (flowers honey) in it to attract the insect, the pollen (male) and pistil (female) are on one flower.
Wind pollination :
Is pollination helped by the wind, usually the flower does not have bright color, have a smaller pollen size (so the wind can carry the pollen), the pollen (male) and pistil (female) are usually not in one flower.
Wind pollinated flowers sometimes look ugly because they don't need to attract bugs.

How do seeds plants reproduce?
Plants reproduce by pollen grains. There are 2 types of pollination: Cross pollination and Self pollination. They are primarily pollinated by means of wind pollination or insect pollination.
Something that carries the pollen if an insect does not?
pollination may also occur through wind, water, or by birds, bats.
Insect-pollinated flowers can also be pollinated by wind why?
Insect-pollinated flowers may still be pollinated by wind as a backup method to ensure successful pollination in case insect activity is limited. Wind can help transfer pollen between flowers when insects are scarce or when weather conditions are unfavorable for insect pollination. This redundancy increases the chances of successful pollination and seed production for the plant.
What are the methods of pollination?
Pollination can occur through various methods, including wind pollination (anemophily), insect pollination (entomophily), bird pollination (ornithophily), and self-pollination (autogamy). Other less common methods include water pollination (hydrophily) and pollination by animals such as bats (chiropterophily) and small mammals (mammalophily).
Pollen grain is transferred to what by a wind or by an animal?
Pollen grains are transferred to the stigma of a flower by either wind (abiotic pollination) or by animals such as bees, butterflies, or birds (biotic pollination). This is an essential step in the process of plant reproduction known as pollination.
What is the difference from self and cross pollination?
Cross pollination is when the wind or a insect carries pollen from one flower to another. Self pollination is when a flower produces pollen and uses it in asexual reproduction.
How do seeds plants reproduce?
Plants reproduce by pollen grains. There are 2 types of pollination: Cross pollination and Self pollination. They are primarily pollinated by means of wind pollination or insect pollination.
What is wind pollination?
wind can Cary pollen grains and it transfers it to different plants or flowers.
What is wind-pollination?
wind can Cary pollen grains and it transfers it to different plants or flowers.
Something that carries the pollen if an insect does not?
pollination may also occur through wind, water, or by birds, bats.
What type of pollination takes place in maize?
Maize is primarily wind-pollinated, as the male flowers (tassels) release pollen that is carried by the wind to the female flowers (silks) for fertilization. Insects can also play a role in maize pollination, but wind is the dominant method.
What are the three ways in which pollination can occur?
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
Wind pollination of grasses wheat and plantain?
Wind pollination is when pollen is carried in the wind
Insect-pollinated flowers can also be pollinated by wind why?
Insect-pollinated flowers may still be pollinated by wind as a backup method to ensure successful pollination in case insect activity is limited. Wind can help transfer pollen between flowers when insects are scarce or when weather conditions are unfavorable for insect pollination. This redundancy increases the chances of successful pollination and seed production for the plant.
What is the difference insect pollination and wind pollination?
Wind pollinated flowers sometimes look ugly because they don't need to attract bugs.
What are the methods of pollination?
Pollination can occur through various methods, including wind pollination (anemophily), insect pollination (entomophily), bird pollination (ornithophily), and self-pollination (autogamy). Other less common methods include water pollination (hydrophily) and pollination by animals such as bats (chiropterophily) and small mammals (mammalophily).
Adaptive value for the shape of pollen grains?
The shape of pollen grains can impact their ability to disperse through the air or be carried by pollinators to reach female reproductive organs for fertilization. Different shapes may be advantageous depending on the method of pollination employed by the plant species, such as wind or insect pollination. For example, spherical grains are often adapted for wind dispersal, while larger and more complex shapes may increase adherence to pollinators for insect-mediated pollination.
