What happens to gymnosperms during pollination?
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.
Pollen is produced by what type of cones?
female cones
In Gymnosperms Male cones usually occur on higher branches and farther from the trunk than the female cones Why would this be?
When pollen from the male cones is released it either falls to the ground by gravity or is dispersed by wind or light breezes. Having the male cone above the female ensures that some pollen will drop onto the female cone via gravity; if the female were above the male no pollen would be able to reach the cone - more a mechanism to ensure self pollination if cross pollination fails. By having the male cones at the our edge of the tree canopy it also improves the pollens chance of being lifted by wind and deposited on a nearby tree (for cross pollination)
What are the similarities and differences between cones and flowers?
they are similar because they both have seeds and sharp hair
Which part of the plant contains the pollen grains?
Flower> Stamen> Anther> Pollen grains.
Where gymnosperms produce all their sex cells?
In cones, female cones produce the seed and male cones produce the pollen

What is difference between seed cones and pollen cones?
Pollen cones are the male pollen-producing cones, and seed cones are the female seed-producing cones in conifer trees.Seed cones are gymnosperms, which means the seeds are not enclosed within an ovary (in Greek, gymno is naked).
How does gymnosperms pollinate?
Gymnosperms pollination occurs after the micro spores are released from the male cone. They travel by wind until they get stuck to a female cone due to a sticky resin. Once stuck a pollen tube is grown and pollination occurs

Where do gymnosperm seeds develop?
Gymnosperms do not produce spore, they produce pollen and seeds. The seeds and pollen are both produced in cones and the seed is "naked", it is not enclosed in an ovary.
How are pollen cones and seed cones are different?
Seed cones (female cones) are much larger than pollen cones (male cones).
Pollen is produced by what type of cones?
female cones
What is the reproductive structures for gymnosperms?
Male and female cones
What structures do gymnosperms produce?
male and female cones
Where are the gametophytes of gymnosperms found?
It is found within the pollen grains.
What are the reproductive structures of genosperms?
Most Gymnosperms are diecious with the male and female reproductive organs on different plants. The male "flower" produces pollen and the female "flower" contains the ovary. Many female gymnosperms produce cones that house the fertilized eggs until the seeds are mature.
