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 the joining of the pollen grain with the ovule?
Pollination.
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
What is the joining of the nuclei from a pollen grain to those of an ovule called?
Fertilization
What do we call joining a pollen grain with a ovule?
Of course, it's called 'Pollination'
What does a pollen grain landing near a ovule produce?
It produces a pollen tube .

The structure that grows from a pollen grain to an ovule and enables a sperm to pass directly to an egg?
pollen tube
What happens when two pollen grains land on the same stigma and after the first grain fertilises the ovule?
When a pollen grain lands on stigma, pollination occurs. The pollen grain germinates and the pollen tube grows through the style. The sperm nucleus travels through the tube (generated by the tube nucleus) and fuses with an ovule which then develops into an embryo (or zygote)

How does fertilization take place in flowers?
the pollen grain lands ot the tip of pistle called as stigma and then pollen tube from pollen grain germinates and it reaches the ovary through style(containing 2 male gamets).. then fertilisation takes place... or is when the male sex cells inside the pollen grains fuses with the female sex cells inside to produce a seed embryo Pollination transfers the pollen grain to the stigma. However, for hertilisation to take place, the nucleus of the pollen grain must fuse with the nucleus of the ovum, which is inside an ovule in the ovary. To transfer the nucleus to the ovum, the pollen grain grows a tube, which digest its way through the tissue of the style and into the ovary. Here it grows around the opening in an ovule. The tip of the tube dissolves and allows the pollen grain nucleus to move out of the tube and into the ovule. Here it fertilises the ovum (egg cell) nucleus.
When a pollen grain joins an ovum?
A polln grain after germination sends a pollen tube in the ovule to release male gametes near the egg cell or ovum.
How many chromosomes would a pollen grain have to compare to an ovule?
Half of the individual cell of ovule except female gametophyte cells
How do the sperms 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.
