Today's class

• Check and correct the homework
  
• Talk about the parts of seeds and their function
• Talk about the lifecycle of a plant
• Soortenquiz (in Dutch)

A brown bean

Outside

• pore/micropyle: absorbing water
  
• Navel/hilum: attachment to pod
  
• Heart shaped bulge
  
• Seed coat: protection

Inside

• Plant embryo 
  (=kiem)
• Seed leaf: food
  (=zaadlob)

micropyle

heart shaped bulge

seed coat

root

plant embryo

leaflet

seed leaf

Water is absorbed through the micropyle.

Germination begins

A seedling has emerged from the seed.

The seedleaves contain food to make growth happen.

The seedleaves are depleted, they will disappear.

Plant continues to grow

The plant wants to reproduce.

The plant develops flowers, these change into new pods.

The cycle starts again
