What else can I help you with?
Does pollen have a nucleus?
Yes, pollen grains have a nucleus. The nucleus contains the genetic information necessary for the pollen to fertilize a plant's ovule.
Can pine pollen meet rose pollen and make a new flower?
No, pine pollen and rose pollen are from different plant species and cannot combine to create a new flower. In general, pollen from one plant species cannot fertilize the ovules of a different plant species.
What is a flower's sperm?
A flower's sperm is contained within the pollen grains. These pollen grains are produced in the male reproductive organs of the flower, called the stamens. When the pollen grains are transferred to the female reproductive organs of another flower, they can fertilize the ovules and lead to seed development.
Where do the pollen grains go after pollination?
After pollination, the pollen grains germinate on the stigma and grow a pollen tube down the style to reach the ovule. The pollen tube delivers sperm cells to fertilize the egg cell within the ovule, leading to the formation of a seed.
What travels to fertilize the ovule?
Pollen travels to fertilize the ovule in plants. Pollen grains contain the male gametes that are necessary for fertilization to occur. The pollen is usually transferred from the anther to the stigma of a flower through various methods such as wind, insects, or animals.
What is needed to fertilize the carpel?
I think that the pollen grains is neede to fertilize the carpel.......
Are pollen grains formed within the stigma?
No, pollen grains are not formed within the stigma. Pollen grains are formed in the anthers of a flower's stamen. The stigma is part of the female reproductive structure of a flower, where pollen grains land and germinate to fertilize the ovules.
Does pollen have a nucleus?
Yes, pollen grains have a nucleus. The nucleus contains the genetic information necessary for the pollen to fertilize a plant's ovule.
How do two plants fertilize?
By sending their male gametes to the female gametes through their pollen tubes after germination of pollen grains.
Can pine pollen meet rose pollen and make a new flower?
No, pine pollen and rose pollen are from different plant species and cannot combine to create a new flower. In general, pollen from one plant species cannot fertilize the ovules of a different plant species.

The time between the act of pollination and actual fertilization in the pine is about?
The time between pollination and fertilization in pine trees is typically around 15 months. This allows for the pollen grains to settle on the female cones, germinate, and eventually fertilize the ovules to produce seeds.
What travels to fertilize the ovule?
Pollen travels to fertilize the ovule in plants. Pollen grains contain the male gametes that are necessary for fertilization to occur. The pollen is usually transferred from the anther to the stigma of a flower through various methods such as wind, insects, or animals.
If a pollen grains in a flower flies to the other kind or the same kind?
The pollen grains from the stamen (male part) of the flower are transferred to the carpel (female part) of another flower to pollinate (fertilize) that flower.
Why do conifers produce more pollen than grains used to fertilize conifer eggs?
Because conifers are pollinated by wind hence to ensure fertilization of each egg clouds of pollen grains are formed.
What is a male cone?
A male cone is a reproductive structure found in gymnosperms, such as pine trees. It produces pollen grains that are spread by the wind to fertilize female cones, resulting in seed production. In comparison to female cones, male cones are usually smaller and produce pollen.
