Stigmas are often described as "feathery" due to their delicate, branched structures that increase surface area for capturing pollen. This feathery appearance aids in the wind or insect pollination processes, enhancing the plant's reproductive success. The soft, fringe-like texture also helps in effectively trapping airborne pollen grains, ensuring fertilization. Overall, the feathery stigma design is an adaptation that promotes efficient reproduction in flowering plants.
What else can I help you with?
Why are the stigmas so large and feathery?
The large and feathery stigmas of certain plants, such as those in the family of grasses, serve to enhance the capture of pollen. Their extensive surface area increases the likelihood of intercepting airborne pollen grains, which is crucial for successful fertilization. Additionally, the feathery structure allows for better adaptation to wind pollination, facilitating the movement of pollen over long distances. This adaptation maximizes reproductive success in environments where pollinators may be scarce.
What cloud is thin white and feathery?
Cirrus clouds are thin, white, and feathery.
What kind of clouds are light and feathery?
Cirrus clouds are light and feathery clouds that form high in the atmosphere. They are composed of ice crystals and are often seen on sunny days, indicating fair weather.
Which describe cirrus clouds?
Wispy, feathery
What are wispy feathery clouds called?
Cirrus clouds
Do insect pollinated flowers have feathery stigmas?
No they do not
What flower has feathery stigmas?
The flower known for its feathery stigmas is the cornflower (Centaurea cyanus). Its stigmas are often long and thread-like, which aids in catching pollen. This feature is characteristic of many plants in the Asteraceae family, where the structure helps facilitate pollination by wind or insects. The feathery stigmas enhance the flower's reproductive success by increasing the likelihood of pollen transfer.
Why are the stigmas on grass often feathery pattern?
so that it can grow
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 would a flower have adaped to wind-pollination?
The anthers hang out of the of the plant so that the wind can get to the pollen and carry it to other plants.
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.
What type of antenna is feathery?
A moth's antenna is usually feathery.
What is the plural of stigma?
The plural of stigma is stigmas or (especially in a religious sense) stigmata.
What cloud is thin white and feathery?
Cirrus clouds are thin, white, and feathery.
