Main processes in reproduction
1) Pollination
transfer of pollen grains from the male part of the plant to the female part of the plant
2) Fertillization
male sex cell fuses with egg cell
3) Dispersal
movement of seeds away from the parent plant to prevent overcrowding
4) Germination
seed grows to become a seedling
