Carpel

Male reproductive organ

Stigma, style and ovary

To attract insects

Produce egg cells (female sex cells) in ovum

Filaments and anther with pollen sacs

Produce pollen grains (male sex cells)

To protect the flower bud against cold and dehydration

Large and brightly coloured, sometimes small and green

Usually green

Pollination 

Self-pollination

Cross-pollination

No pollination

When pollen on the anther of a flower reaches the stigma of a flower on the same plant

When pollen from one plant reaches the stigma of a flower on another plant 

When pollen of one species (=soort) reaches the stigma of a flower of another species
