Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
What is a ovule part of the female flower?
The ovule is the part of the flower where the embryo sac is housed, and the embryo sac contains the female gamete (egg), which, when fertilized by the sperm in a pollen grain, will produce a zygote. What was once a flower will become a fruit. The zygote develops in the ovule, and forms the seed, which will eventually be dispersed from the fruit to start a new generation. So, the ovule is analogous to the pollen: one contains the female gamete, and the other contains the male gamete.

What are the steps that happen between pollination and fertilization?
After pollination, the pollen grains germinate and form a pollen tube that grows through the style towards the ovary. Once the pollen tube reaches the ovary, it enters the embryo sac and delivers the sperm cells. Fertilization occurs when one sperm cell fuses with the egg cell to form a zygote, while another sperm cell fuses with a polar nucleus to form the endosperm, which provides nourishment to the developing embryo.
What is a pollen-producing sac?
what has a sticky surface where pollen lands
What is the function of the pollen sacs in a flower?
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
What do a anther do in a flower?
The anther holds the pollen sac in Hawaiian flowers or any other kind of flowers.

What is the function of pollen grains?
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.

Pollen-containing sac that sits atop the filament?
Anther
What is the fate of the tube nucleus in the pollen tube?
Tube nucleus generates after guiding the pollen tube into the embryo sac
What are the parts of flowers involved in fertilization?
The female parts of the flower are the ovary, eggs, pollen tube, pistil, and stigma. The male parts of the flower are the stamen, anthers, and pollen. The eggs of the flower are kept in the ovary; pollen from other flowers' anthers and stamens is received by the stigma and filters down through the pollen tube. The pollen fertilizes the eggs; fertilization is complete.
Pollen containing sac that sits atop the filament?
The stamen produces pollen, which are the male sex cells of plants. This is then collected into the anther of the stamen.
