Which part of a flower receives pollen during pollination?
stigma True, but Ill explain more... Pollen from the Stamen- (male reproductive parts of a flower) must land on the Pistil-(female reproductive parts of a flower) for fertilization to occur, and thats when the seed grows in the ovary. :)
What is it called when the pollen has gone down the pollen tube and enters the ovary?
Pollination
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.
During sexual reproduction in a flowering plant a pollen tube grows down through the?
The pollen tube grows through the stigma and style in the pistil, to reach the ovaries where the pollen may fertilize an egg.
How close to the egg can the pollen grain get?
when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with the egg.
How pollen tube grows down through the style?
The pollen tube grows down to the style after the pollination happen.
What do you call the transfer of pollen from one plant to another?
If the plants are compatible cross pollination will occur.
Does pollination occur when pollen combines with an egg?
Pollination is when the pollen grain lands on the stigma. It then grows a pollen tube and part of it, the actual male gamete, travels down and fuses with the ovule (egg) which is the actual fertilization.
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.
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 seed are produced?
1 Once the pollen has landed on the sticky stigma of a pistil, a pollen tube starts to grow.2 The pollen tube grows from the pollen grain down the style.It grows into the ovary until it reaches the ovules.3 The sperm travels down the pollen tube and fertilizes the egg.
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.

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.
