What forms when stigma and pollen develop?
when the pollen comes in contact with the stigma.. the pollen tube is formed. that then goes into the ovary and fertilizes with the ovule.
What happens when the pollen grain falls on the stigma?
when pollen grains falls on stigma, it creates a pollen tube which dilivers pollen grain and fuses with female gametes present in the ovule
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.
What process happens when pollen falls on a flowers pistil?
Pollination brings together the gametes of a flower and it occurs when a pollen grain of the right kind lands on the stigma of the pistil. Each pollen forms a tube that grows down through the pistil and reaches the ovule in the ovary. One of the nuclei in the pollen tube unites with the egg nucleus in the ovule to form a zygote. The other sperm nucleus combines with another bigger nucleus in the ovule which develops into the endosperm.
Grows from the pollen grain to the ovule?
Pollen tubes grow from the pollen grains to the ovules. Lipids on the surface of the stigma stimulate growth of the pollen tubes. Self sterile plants prevent themselves from growing seeds by not creating these lipids.
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.
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.
The pollen tube fertilizes the?
ovule
When a pollen grain joins with an ovum?
A polln grain after germination sends a pollen tube in the ovule to release male gametes near the egg cell or ovum.
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
What does a pollen grain landing near an ovule produce?
It produces a pollen tube .
What does a pollen grain landing near a ovule produce?
It produces a pollen tube .
Does a pollen tube deliver one sperm to an ovule?
Yes
What are the examples of chemotropism?
Growth of pollen tube towards the ovule!
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.
What does the pollen tube grow towards?
maybe it's because of the ovule.
What is the term for the entry of the pollen tube into the ovule through the micropyle?
mesogamy
