What is the function of the pollen grains in the flower?
It takes the sperm into the male reproductive organ and then new flowers grow.
After pollination the pollen grains begin to?
Pollen grains and on stigma of a compatible plant; the pollen grains germinate and grow down the style and into the ovary. Once in the ovary a sperm nucleus from the pollen grain fuses with the ovule (and forms into a zygote or embryo). The pollen tube then degenrates and the ovule forms into a seed.
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
What structure transports sperm in the ovule in flowering plants?
The pollen tube is a structure designed to help a particle of pollen, the male side of the plant fertilization process, to access the egg cell in the female part of the plant. The egg cells are typically protected by cell walls and shells designed to keep them in place and protect them from outside elements. Pollen particles create pollen tubes to reach through these walls and access the egg cell.
What does a pollen grain landing near an 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 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 transfer pollen from stamen to ovules?
A pollen tube grows from the pollen grain down through the style. The pollen tube enters the ovary and reaches an olvule. The sperm then travels down the pollen tube and fertilizes the egg in the ovule. So a 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 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.
The pollen tube fertilizes the?
