Flower power

This week we learnt about various plant structures from root to stem, leaves, and flowers!  We learnt about diffusion and osmosis and how water enters the roots of plants.  This demonstration shows how water (and food colouring) travels up the stem and out to the leaves and flowers.  Also the water leaves via transpiration but the colour stays in the pedals.  Beautiful.

 A great explanation here
