After the pollen grains land on the stigma what begins to grow from a cell in the pollen?
the pollen tube
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
Does pollen tube grow before or after pollination occurs?
Before
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.
What does the pollen tube grow towards?
maybe it's because of the ovule.

Does Labiatae grow in France?

Why will a plant grow a flower?
to attract bees to spread pollen

Can the flower bears food if the stigma is cut off?
No, because pollen cannot reach the ovary. Stigma is necessary for trapping pollen and for rehydration of pollen tube to grow. So no fertilization occurs.
What happens from the time pollen lands on the female part of the flower until the seed forms?
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA
Why do grasses produce many pollen grain?
Like most plants, grass uses sexual reproduction in the form of pollen to grow more. Because this pollen is spread by wind, there needs to be quite a bit of it for the pollen to reliably seed many flowers.
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.
What stimulates the pollen to grow?
Lipid that is found on the surface of the stigma stimulates the growth of the pollen tube, which enters through the style to the ovary. Hope that helps
