The path of pollen through the pistil begins when pollen grains land on the stigma, the sticky surface at the top of the pistil. From there, a pollen tube grows down the style, which is the elongated part of the pistil, toward the ovary. As the pollen tube reaches the ovary, it releases sperm cells that can fertilize the ovules, leading to seed development. This journey is crucial for successful reproduction in flowering plants.

What female part of the flower helps the pollen down to the ovule?
The Stigma is the female part of a flower that receives the pollen during fertilization.
How does the pollen grains tube reach the ovary?
Pollen tubes are extensions of pollen grains that grow and elongate to penetrate the ovary. They are guided by chemical signals released by the ovary, which direct the path of the pollen tube towards the ovule where fertilization can occur.

Describe a path of the light ray that hits a mirror after passing through its focus?
It is reflected back parallel to the principal axis. (apex)
Describe the path electrons take in a simple flashlight circuit?
In a simple flashlight circuit, electrons flow from the negative terminal of the battery through the metal conductor to the light bulb, where they pass through the filament, creating light. The electrons then continue flowing through the metal conductor to the positive terminal of the battery, completing the circuit.
How does the pollen grains tube reach the ovary?
Pollen tubes are extensions of pollen grains that grow and elongate to penetrate the ovary. They are guided by chemical signals released by the ovary, which direct the path of the pollen tube towards the ovule where fertilization can occur.
