A bee transfers pollen from the anther to a stigma by visiting flowers to collect nectar and pollen as food. While foraging, pollen grains stick to the bee's body due to static electricity and the hairy texture of their bodies. When the bee moves to another flower, some of this pollen is brushed off onto the stigma, facilitating cross-pollination, which is crucial for plant reproduction. This process enhances genetic diversity in plants and promotes healthy ecosystems.

In some plants the pistils don't form until a few days after the stamens do how might this plant keep a plant from self-pollinating?

For a flower to be pollinated, pollen from an anther (which is located at the top of the stamen) needs to reach a stigma (at the top of the pistle.) Some plants are genetically capable of pollinating themselves if their own pollen reaches their own stigma; some plants are not capable of self pollination under any circumstances. For plants that can genetically self pollinate, but would prefer not to, they can avoid this by having their pistil and pollen/stames mature at different times. If the stamens mature first, the pollen will be dispersed by animals or wind or whatever dispersal mechanism it relies on. Then by the time the pistil is ready to be pollinated, there is no pollen left in that flower to land on the stigma.


Sticky secretion on the scales of seed cones traps?

A sticky secretion on the scales of seed cones traps pollen grains. Structure is produced by a pollen grain that lands near an ovule is pollen tubes.


What might pollen stick to on a mammal pollinator?

Bats are well known mammalian pollinators. As the bat buries its face deep into the blossoming flower to get its nectar, the pollen sticks to the bat's face, specifically its facial hair, nose, lips and whiskers...and perhaps even the ears of smaller bats.


How might pollen germination and growth be controlled?

Pollen germination and growth can be controlled by manipulating environmental factors such as temperature, humidity, and light. Chemical treatments, such as hormones or inhibitors, can also be used to regulate pollen germination and growth. Additionally, genetic manipulation can be employed to develop transgenic plants with desired pollen germination and growth characteristics.


What are three ways plant sperm and eggs might travel to get together for fertilization?

Insect pollination: Insects like bees and butterflies transfer pollen from the male part of one plant to the female part of another plant. Wind pollination: Pollen grains are carried by the wind to reach the female reproductive organs of plants, facilitating fertilization. Water pollination: Some aquatic plants release their sperm and eggs into the water, where they meet and fertilize.

How does the kowhai flower pollinate?

Kowhai flowers are pollinated by birds, mainly tui and bellbirds, that extract nectar from the flowers while inadvertently transferring pollen between flowers. The curved shape of the flowers and positioning of the anthers and stigma allow for effective pollen transfer during feeding.

What stigma might a defendant acquire once he is convicted?

A stigma against lawyers! Aka prosecutors.


Grows from the pollen grain to the ovule?

Pollen tubes grow from the pollen grains to the ovules. Lipids on the surface of the stigma stimulate growth of the pollen tubes. Self sterile plants prevent themselves from growing seeds by not creating these lipids.


What is polinators?

Transfer of pollen grains in seed plants from the stamens, where they form, to the pistil. Pollination is required for fertilization and the production of seeds.


Which perspective focuses on the stigma that a defendant might acquire once he or she is convicted?

Nonintervention


Why cant you bring flowers into a hospital?

because some flowers might have pollen and some people might be allergic to them


Does sperm cell grows out of a pollen grain?

No, sperm cells do not grow out of a pollen grain. In plants, sperm cells are produced within the pollen grain, and they are involved in fertilization when the pollen grain reaches a female reproductive structure. Each pollen grain contains two sperm cells.

How can pollen be used to work out where people or objects have been?

the pollen might stick to their clothes, hands/fingers and hair, which can be an easy source to find out where the person has been.


What do honeybees collect?

If you might have noticed a recent answer, which was pollen, that answer is wrong. Bees collect nectar, which they turn into honey. pollen sticks to their legs and falls onto other flowers. this is called pollination.


What is a pollinator and how might one be attracted to a plant?

A pollinator is also referred to as a "vector" or "agent". This is the method or means whereby pollen is transferred from the anthers of one plant to the stigma of another. Agents can be living things such as bees, birds, ants, beetles, bats etc.; they can also be nonliving such as wind and water.
