A structure grown by a pollen grain that contains two sperm nuclei is called what?
The two nuclei found inside each pollen grain are called tube nucleus and germ nucleus.
How many chromosomes are there in the female nucleus of a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.
Why used the mature pollen grain in pollen germination experiment?
this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell for 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.
How does pollen that fertilizes the egg reach the ovule?
Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.
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'

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.
