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.
What is a rockets path called?
A rocket's path is typically referred to as its trajectory. This trajectory is influenced by factors such as thrust, gravity, and air resistance, determining the path the rocket will follow as it travels through space.
Where does the blood flow begin at?
The circulatory system is like a circle, so there is no real beginning or end. So when you describe it, you could start where ever you want. People often start in the heart, but you could start anywhere along the path. Here is a very simplified path through the circulatory system: Right heart to lungs to left heart to arteries to capillaries to veins and back to right heart.
Can water take only one path through the water cycle?
No water can follow one of several paths that form the detailed cycle.
Potentail hazards in running?
If you suffer from hayfever or have bad allergies, pollen is a hazard when running through fields. If you are running down a path, the stones on the path could be a hazard if they are uneven.
What is the term used to describe a path for electrons to flow?
The term used to describe a path for electrons to flow is a "circuit." A circuit is a closed loop that allows the flow of electricity from a power source through components and back to the source.
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.
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.

What are four ways to describe an objects motion?
Speed: How fast an object is moving. Direction: The path an object is following. Acceleration: How quickly an object's speed or direction is changing. Trajectory: The curved path or motion of an object through space.
