Pollen Reaches the Ovule
Open to everyone until Thursday, October 1
To keep it, print it while it is open.
A pollen grain lands on the sticky tip of a flower’s pistil. It grows a thin tube down to the ovule, and male cells travel through the tube to start fertilization.
In the picture
- A pollen grain resting on the stigma
- The pollen tube growing down through the style
- The ovule at the base of the pistil
- Male cells travelling inside the tube
Examples
- A bee carries pollen from one apple blossom to another.
- Wind blows grass pollen onto the sticky tip of a nearby flower.
Key takeaways
- The pollen tube is grown by the pollen grain itself.
- Male cells travel inside the tube to reach the egg cell in the ovule.
