What else can I help you with?
How are seeds with feathery structures scattered?
Seeds with feathery structures are scattered by the wind. The feathery structure allows the seed to be easily carried by air currents to new locations. When the wind blows, the seeds are lifted and dispersed, helping the plant to spread and colonize new areas.
How stigma helps in the wind pollination?
Depending on the type of pollinators, the pollen grains may be sticky or light. Exine present on the pollen grains as the outermost covering layer is contributed by the tapetum cells. Reaching on the stigma after pollination, the stigmatic cells interact with the material of exine to determine the compatibility of the pollen to allow its germination for fertilization.
What transfers the pollen from the stamen to the stigma?
Insects, animals, wind, or water can transfer pollen from the stamen to the stigma of a flower in a process called pollination. This transfer of pollen is essential for the fertilization and reproduction of the plant.
How can plants cross pollinate?
By landing pollen grains of another compatible genotype on the stigma of a plant by insect, bird, water, wind or mammals
When pollen moves from the?
Pollen moves from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower through pollination. This transfer can occur via wind, insects, birds, or other pollinators. Successful pollination leads to fertilization and the formation of seeds.
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.
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.
How are seeds with feathery structures scattered?
Seeds with feathery structures are scattered by the wind. The feathery structure allows the seed to be easily carried by air currents to new locations. When the wind blows, the seeds are lifted and dispersed, helping the plant to spread and colonize new areas.
What is the function of the stigma in the plant?
The stigma of the flower is used to collect pollen. When pollen is carried by wind or animals it gets stuck onto the stigma by a glue that the stigma produces.
Flowers without petals are pollenated by whom?
Usually by the wind.
How does wind pollinate?
On maturity of pollen grains , the anther lobes burst open and the pollen grains released in large amonut are carried by wind to several meters away to settle on feathery stigma as in case of plants of grass family.
How stigma helps in the wind pollination?
Depending on the type of pollinators, the pollen grains may be sticky or light. Exine present on the pollen grains as the outermost covering layer is contributed by the tapetum cells. Reaching on the stigma after pollination, the stigmatic cells interact with the material of exine to determine the compatibility of the pollen to allow its germination for fertilization.
How do you pollinate primroses?
Most pollination takes place with the help of insects and wind. The purpose of pollination is to transmit the pollen from one plant to the stigma of another plant.
Who do you think the stigma is sticky?
Wind pollinated flowers have sticky stigma
What transfers the pollen from the stamen to the stigma?

Which flower thus stigma feel sticky?
Wind pollinated flowers have sticky stigma
