What does pollen join with to make seeds?
pollen joins an ovule to make seeds
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.
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 happens when the pollen tube joins the ovule?
If The Pollen Tube Joins The Ovules They Will Have Fertilization And At The End After The Ovules Will Become The Seeds It Is One Or Many Seeds

What is the joining of the male nucleus from the pollen grain with the egg cell in the ovule called?
Its fertilization
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
What is it called when a pollen grain joins with an ovary?
When viable and compatible pollen grains are brought in the vicinity of ovule having mature embryosac, gametic union will take place. This is called fertilization.
What does a pollen grain and ovule each contain?
Pollen grains contain the male gametes required for sexual reproduction of a plant/ flower. These are haploid, and only contain half the full set of chromosomes; the other half is contributed by the female gamete (or ovule).A grain of pollen contains:a larger vegetative cell (also called the tube cell) inside of which is aa smaller germ cell (also called the generative cell).The pollen grain "germinates" on the stigma of the receptive flower and grows down the style, once it reaches the ovule the germ cell/ nucleus fuses with the nucleus of the ovule and an embryo is formed
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.
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.
What is the fusion of pollen and ovule called?
pollination
