What are the sturctures that produce the male gametophyte in angiosperms called?
stamen, pollen pod
What is the joining of the male nucleus from the pollen grain with the egg cell in the ovule called?
Its fertilization
How do the sperm nuclei in a pollen grain reach the egg nucleus in an ovule?
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.
The generation of a plant responsible for producing gametes is the?
Pollen are produced in the anther of the stamen, which is the male part of the plant. The pollen is transferred to the ovule of the ovary (the female part of the plant). Both pollen and ovule are haploid gametes.
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 it called when a pollen nucleus joins with the ovule nucleus?
Pollination
What is the joining of the nuclei from a pollen grain to those of an ovule called?
Fertilization
Is the planting of a pinto bean asexual or sexual?
sexual, as the bean seed was produced from the fusion of a male pollen grain and a female ovule
What are the sturctures that produce the male gametophyte in angiosperms called?
stamen, pollen pod
When a pollen grain joins with an ovam what is called?
Fertilization resulting in the formation of a zygote or embryo; technically, the pollen grain does not join with the ovule. A pollen tube grows from the pollen grain - this contains the gamete which fuses with the ovule.
What do we call joining a pollen grain with a ovule?
Of course, it's called 'Pollination'
How does fertilization in plants?
the pollen grains after landing on the stigma germinate to send out pollen tubes through which the male gametes reach near the egg cell of embryo sac in the ovule to fuse with. this fusion of male and female gametes (egg cell) is called fertilization.
When pollen from one plant fertlizes the ovule of another plant it is called?
cross pollination
What Sex cells in plants are called?
male = pollen female = ovule or Male consisting of the anther and filament is called the Stamen Female consisting of the Style, Stigma and ovule called the Carpel
Where is pollen form?
In the Anther
The pollen tube fertilizes the?
ovule
What are sex cells in plants?
male = pollen female = ovule or Male consisting of the anther and filament is called the Stamen Female consisting of the Style, Stigma and ovule called the Carpel
