Slide 8 - Tekstslide

How can pollen of one flower reach another flower?

Slide 9 - Open vraag

Insect pollination
Wind pollination

Slide 10 - Tekstslide

Pollination = transfer of pollen grains from an anther to a stigma of a flower of the same species 

Slide 11 - Tekstslide

self-pollination = same plant;    cross-'' is with another plant 

Slide 12 - Tekstslide

Wind pollination

  • Flowers are small and inconspicuously*coloured
    - Stamen hanging out in the wind
    - Stigma's large and feather shaped*
  • Don't produce nectar
  • Pollen grains are very light & small

(mostly grasses and trees)

hay fever?

Slide 13 - Tekstslide

Pollination by animals

Slide 14 - Tekstslide

Which animals can
pollinate flowers?

Slide 15 - Woordweb

Pollination by animals
(insectflowers) 
- large and strikingly* coloured petals (UV)
- scent and nectar.
- sticky pollen grains

Slide 16 - Tekstslide

Slide 17 - Video

Slide 18 - Link

6.2.2 You can describe what pollination is.
6.2.3 You can explain the difference between cross-pollination and self-pollination.
6.2.4 You can list the features of insect-pollinated flowers and wind-pollinated flowers.

Insect-pollinated flowers
Wind-pollinated flowers
The petals are coloured 
The petals are small and green
The flowers have nectar and are scented
The flowers don't have nectar
Pollen sacs are outside the flower
Pollen sacs are inside the flower
Stigma is usually inside the flower
Stigma is usually outside the flower
Stigma are feathery (geveerde vorm)
pollen grains are rough and sticky
Pollen grains are smooth and light
