What is the fusion of pollen and ovule called?
The fusion of pollen and ovule is called fertilization. This process involves the union of the sperm cell from the pollen with the egg cell in the ovule, resulting in the formation of a zygote, which eventually develops into a seed.
What does the pollen do in a plant?
Pollen grows down the style of a flower and produces 2 sperm which then fertilize an ovule and another cell (which provides energy for the ovule).
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
What does a pollen grain landing near an ovule produce?
If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.
What is the space above the nucellus in a pine ovule called?
The space above the nucellus in a pine ovule is called the pollen chamber. This is where pollen grains land and germinate before fertilizing the egg cell within the nucellus.
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'
What is transferring pollen grains from another to the stigma of a flower?
when pollen grain are transferred from the stigma the ovule of the flower , whats takes place
What does the ovule develop into when it is fertilized by nectar from another plant?
When an ovule is fertilized by nectar from another plant, it develops into a seed. The nectar acts as a source of pollination, transferring pollen to the ovule, which then goes through fertilization to form a seed.
What are the sturctures that produce the male gametophyte in angiosperms called?
The structures that produce the male gametophyte in angiosperms are called anthers. Anthers are located on the stamen of the flower and contain pollen sacs where microspores develop into pollen grains through meiosis and subsequent mitotic divisions.
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
