If a plant has a sticky stigma is it wind or insect pollinated?
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.
On which flower does the stigma feel sticky?
in the gumamela flower
What features of a pollen grain makes it suited for being brushed off an insect?
A pollen grain's surface is often rough and sticky, allowing it to adhere to an insect's body as it moves from flower to flower. Additionally, the shape and size of pollen grains match well with insect hairs, making them easy to brush off as the insect travels. Lastly, the lightweight nature of pollen grains makes them easily dispersed by the movement of insects.
What does catch pollen from insects or the wind?
Plants with sticky stigmas catch pollen from insects, as the pollen adheres to the stigma when the insect visits the flower. Plants with feathery stigmas catch pollen from the wind, as the lightweight pollen grains are carried by the wind to land on the stigma.
Why is the sticky substance on the top of the stigma important?
The stigma of a flower is sticky in order to aid in the reproduction of the flower. The stickiness allows pollen to adhere to the stigma, a sexual organ. This sticky stigma also prevents unwanted organisms and insects from penetrating the plant.
If a plant has a sticky stigma is it wind or insect pollinated?

What is the different in pollen at wind and insect pollination?
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.
Characteristics of insect wind and water pollinated flowers?
Insect-pollinated flowers are often brightly colored, have nectar guides or fragrances to attract insects, and have sticky pollen grains that adhere to insects for transfer. Water-pollinated flowers are often dull in color, lack nectar or fragrance, and produce large quantities of light, buoyant pollen grains that can be carried through water currents for dispersal. Additionally, water-pollinated flowers tend to have feathery stigmas that can easily capture pollen carried by water.
Would you expect pollen grains of wind -pollinated flowers to be sticky?
The pollen grains of wind pollinated plants are generally smooth and light. These are not sticky to avoid clump-sing. These are produced in large numbers to ensure landing some pollen on the feathery or netted stigmas.
On which flower does the stigma feel sticky?
in the gumamela flower
Who do you think the stigma is sticky?
Wind pollinated flowers have sticky stigma
Which flower thus stigma feel sticky?
Wind pollinated flowers have sticky stigma
Why is buttercups pollen sticky?
Buttercups produce sticky pollen as a way to adhere to the bodies of pollinators, such as bees and butterflies, making it easier for the pollen to be transported between flowers for successful pollination. The stickiness helps the pollen grains remain attached to the insect as it moves from flower to flower, increasing the likelihood of successful reproduction for the plant.
What flower does the stigma feels sticky?
Sticky stigma is generally present in wind pollinated flowers.
What are some characteristics and adaptations of flowers pollinated by beetles?
Flowers pollinated by beetles tend to have strong, fruity or fermented odors that attract beetles. These flowers are often dull in color, such as white or cream, as beetles do not rely on color cues for pollination. Additionally, beetle-pollinated flowers may have sturdy structures and surfaces for the beetles to easily crawl and forage for nectar and pollen.
Why is flowers stigma sticky?
to catch pollen ---> novanet
How can you tell by looking that a flower is insect-pollinated?
Bright-colored, nectar-containing, nice-scented petals with firm, sticky pollen-producing anthers and firm, sticky-coated stigma inside the blooms are what tell -- just by looking -- that a flower is insect-pollinated. The structural looks back up the function-serving purposes of attracting insects (bees, butterflies) to fulfill feeding requirements through nectaring in order to have pollen moved between male and female parts for reproduction.
