How nucleus from a pollen grain fertilize a female egg cell?
How the nucleus from a pollen grain fertilize a female egg cell
How the nucleus from a pollen grain fertilizers a female egg cell?
How the nucleus from a pollen grain fertilize a female egg cell
After pollen grows a tube down the style?
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
What is difference between ungerminated pollen grain and germinated pollen grain?
The germinated pollen grain is empty of the male gamete nucleus.
How do you xxplain the structure of the pollen grain describe the development of pollen grain and male gamete?
While still attached to the anther, the nucleus of the pollen grain divides, producing two nuclei, one of which becomes the tube nucleus, the other is called the generative nucleus. The generative nucleus divides again, forming two sperm cells. Once the pollen grain is released from the anther, it is transported (by wind or fauna) to the stigma of the female flower. Once a pollen grain has landed on the stigma, it begins to grow a pollen tube (there are three nuclei in the pollen tube, one from the tube nucleus, and the two sperm). When the pollen tube reaches the ovary, both sperm cells enter the ovule, one fuses with the egg nucleus, the other fuses with polar nuclei that is also inside the ovule, forming the endosperm.
How does the pollen tube nucleus function in fertilization?
The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary
What is the fate of the tube nucleus in the pollen tube?
Tube nucleus generates after guiding the pollen tube into the embryo sac
What is it called when a pollen nucleus joins with the ovule nucleus?
Pollination

A pollen grain forms a tube leading to the flower's what?
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
What is the function of the sperm nucleus in plants?
the sperm nucleus is found in pollen grains and directs the growth of the pollen tube to the ovule in the ovary, it then degenerates
After pollen grows a tube down the style?
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.

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.
What is the transer of pollen grains to ovules?
It contains a tiny egg nucleus which will fuse with nucleus of the male cell.
