What is the opening to the ovule of a conifer called?
The micropyle
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
Does micropyle in the ovule help in diffusion of respiratory gases?
yes
When pollen connects with an ovule in the ovary?
Esphogatioues
What does a pollen grain landing near an ovule produce?
It produces a pollen tube .
What is the function of the micropyle?
The micropyle opening allows the pollen tube to enter the ovule for fertilization. It absorbs water for germination. It provides for the diffusion of respiratory gases.
How does a pollen grain travel through the parts of a flower to finally become a seed?
The pollen grain released from the anther lobe during anthesis reaches the stigma by pollination. Thereafter, it germinates on the compatible stigma to send pollen tube to the micropyle of the ovule inside the ovary. The male gametes from the pollen grain are transferred to the embryo sac for fertilization and the ovule is converted into a seed when zygote develops into an embryo.
What is the opening to the ovule of a conifer called?
The micropyle
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.
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
Does micropyle in the ovule help in diffusion of respiratory gases?
yes
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.
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.
The pollen tube fertilizes the?
ovule
Where is pollen form?
In the Anther

Where does pollen first enter the pistil?
The pollen first lands on stigma of the pistil and on germination makes its way through the style to the ovule inside the ovary.
