Gymnosperms do not produce flowers (as opposed to angiosperms), so there is nothing to attract pollinating insects. As a result, they depend on the wind to blow the pollen from the male to the female cones. Pollination can also occur if the male cones are present at the same time and situated above the female cones. In this case self-pollination can occur when the pollen simply falls or blows downward.

What happens once the pollen lands on the stigma?
Pollination
Why do gymnosperms and angiosperms produce pollen and seeds?
The group that produces fruits and vegetables are angiosperms. Gymnosperms produce conifers like cedar and softwoods like pine and fir.
Does the wind often carry pollen from male cones to female cones in gymnosperms?
Yes, wind is a common method for pollen dispersal in gymnosperms. Male cones produce pollen grains that are lightweight and easily carried by the wind to female cones where they can fertilize the ovules. This wind-mediated pollination allows gymnosperms to reproduce without the need for animals or water.
What is the difference between pollination and fertilization gymnosperms vs angiosperms?
In gymnosperms, pollination refers to the transfer of pollen to the female ovule, while fertilization is the fusion of the male gamete with the female gamete within the ovule. In angiosperms, pollination occurs when pollen reaches the stigma of the flower, and fertilization happens when the male gamete fuses with the female gamete in the ovule, which is enclosed in the ovary.
What are two ways that a plant can cross- pollinate?
during pollination, pollen from the anther (male part) is carried to the sigma (female part). Fertilization happens when a sperm from the pollen moves through the sigma and enters an egg in an ovule. By insects visiting flowers and by wind velocity
In what ways does pollination in gymnosperms differ from pollination in angiosperms?
One main difference is that gymnosperms typically rely on wind for pollination, while angiosperms often rely on animals like bees for pollination. Additionally, gymnosperms have exposed seeds, while angiosperms have seeds enclosed within a fruit. Finally, gymnosperms do not produce flowers, while angiosperms do.
What happens during the processes of cross-pollination and self-pollination?
there is not to big of a differents
How gymnosperms and angiosperms compare?
Both have wind pollination. Hope this HELPS!! :)
Which happens first pollination or fertilation?
Pollination. Fertilization is what occurs after pollination.

What doese pollination mean?
Pollination happens is when the pollen goes into the ovary.

Why do gymnosperms and angiosperms produce pollen and seeds?

How does gymnosperms pollinate?
Gymnosperms typically pollinate through the transfer of pollen grains by wind. Male cones release pollen, which is carried by the wind to female cones for fertilization. This method allows gymnosperms to reproduce without the need for external agents like insects.
Pollen grains move from a flower's stamen to it's pistil during what?
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
Does the wind often carry pollen from male cones to female cones in gymnosperms?
Yes, wind is a common method for pollen dispersal in gymnosperms. Male cones produce pollen grains that are lightweight and easily carried by the wind to female cones where they can fertilize the ovules. This wind-mediated pollination allows gymnosperms to reproduce without the need for animals or water.
