10. SHOCK WARNING! Take notes… * All plants have MALE and FEMALE parts!
* They reproduce by the process of pollination.
* Pollen from the MALE part of one plant must transfer to the FEMALE part of a different plant.

11. Take notes: stamen pistil The MALE part that produces pollen.
The FEMALE part that gets fertilized by pollen, and grows seeds in the flower’s ovaries.

12. Tube that pollen travels down
Read this slide:
The pistil has 3 parts

(female part)
Is ticky
Catches pollen
