Plant parts
1. Receptacle : the other parts of the flower are attached to this.

3. Nectary: glands, producing nectar. 
Nectar = sweet liquid.


Slide 9 - Tekstslide

Plant parts
Petals = the coloured leaves for attracting insects.

Pistil = used for the reproduction.

Stamens = also for the reproduction.

Slide 10 - Tekstslide

Voortplantingsorganen
Stamen
  • Anter = produces a large amount of grains/pollen (male gametes). 
  • Filament 

Pistil
  • Stigma
  • Style 
  • Ovary = contaiins ovules that each contain an egg cell (female gametes). 


Slide 11 - Tekstslide

How does pollen reach te pistil? 
Pollination = transfer of pollen from the stamens to the pistil

  • Cross- pollination = when the pollen of one flower is transferred to the pistil of the flower of another plant

  • Self-pollination = when the pollen is transferred to the flowers of the same plant

Slide 12 - Tekstslide

Cross-pollination, self-pollination or no pollination?

Wind-pollinated flowers
Less striking small green flowers withouw scent. Stamens and stigma hang out far from the flower.
