What else can I help you with?
Is pollen more or less likely to be dispersed by wind during rainy weather?
Yes. The rain prevents the Pollen from from being air-borne.Answer Generally, yes. The pollen grains are "washed out" of the atmosphere.
What special features do wind pollinated flowers have?
-Flowers are small, inconspicuous with stalks well above leaves to increase exposure to air currents -Have large anthers, often with long filaments that hang well outside the flower allowing them to sway and shake out pollen grains at the lightest breeze -Have green like bracts rather than petals and do not have scent or sepals -Long, flexible, feathery, stigma that is projected outside the flower. Acts as a net to trap pollen grains -Pollen grains are light, smooths and large in quantity -No nectaries
What time of the day is pollen the worst?
Pollen levels are typically highest in the early morning, often between 5 AM and 10 AM, when plants release pollen into the air. Additionally, warm, dry, and windy conditions can exacerbate pollen levels throughout the day. Conversely, pollen counts tend to decrease in the late afternoon and evening as temperatures drop and humidity rises.
Where is Pollen located in plants that rely on wind for pollination?
In plants that rely on wind for pollination, pollen is primarily located in the anthers of the flowers. The anthers produce and release pollen grains into the air, where they can be carried by the wind to other flowers. These plants typically have lightweight, dry pollen to facilitate this process, and their flowers are often small and not brightly colored, as they do not need to attract pollinators.
How do you collect seeds gazania?
To collect seeds from gazania plants, allow the flower heads to dry on the plant. Once the seeds are fully matured, cut off the flower heads and shake the seeds out into a paper bag or container. Store the collected seeds in a cool, dry place until you are ready to plant them.
Do roses have pollen?
Yes carnations have seeds When the flower has finished blooming there will remain seed pods where the flower was just save these and dry them and you can plant them next year.
How can a plant breeder cross-breed two varieties even though the pollen is produced two weeks before the other stigma is ready to receive it?
Plant breeders can use techniques like emasculation and artificial pollination to cross-breed two varieties with staggered pollen and stigma maturity timelines. Emasculation involves removing the anthers of a flower before they release pollen, and then manually applying pollen from another plant once the stigma is receptive. This method allows breeders to control the timing of pollination and successfully cross two varieties with asynchronous flowering schedules.
Pollen and seeds evolved in response to what?
it evolved in response to dry land environments

What is used as spice of dry flower bud?
clove
How does dry ice exist?
Dry ice is simply frozen carbon dioxide
How can one effectively preserve pollen for future use?
To effectively preserve pollen for future use, one can store it in a cool, dry place in an airtight container. It is important to keep the pollen away from moisture and light to maintain its viability. Additionally, freezing the pollen can help extend its shelf life.

How does hummingbird feed on cactus?
Hummingbirds feed on cactus by probing the flowers with their long, specialized bills to access the nectar. Many cacti have brightly colored and tubular flowers that attract these birds, which are critical pollinators. As hummingbirds move from flower to flower, they inadvertently transfer pollen, aiding in the plant's reproduction. Additionally, some species may also sip moisture from the cactus pads during dry conditions.
Why do flowers pollinated by wind produce lots of dry pollen?
It is because they they are light so they can be blown easily by the wind
