Pollen
• Tiny structures that will later become
sperm cells
• Spread by wind and animals
Pollination
Pollination
• Some pollen is brushed onto the stigma
• The sperm travels down the pollen tube
until it reaches the ovule (egg cell)
• The sperm (pollen) and egg (ovule) join to
form a seed. This part is called
fertilization.
