Green and Growing: The Life of a Seed

As you know, there is a vast number of different kinds of plants growing all over the world, from snowy slopes to Amazon rain forests to dusty deserts: plant life is everywhere. So how does it all work? Lets start with seeds.

 

 The Life of  a Seed

It all started when my friend Nic’s very favourite chicken, Rosie became broody. Rosie laid some eggs and sat on them very carefully for a very long time. But the eggs didn’t hatch and Nic realised that they were probably never going to. Sometimes they just don’t.

Poor Rosie – all that patient waiting for nothing.
