Plant Seeds Use "Mini Brains" to Decide When to Sprout (STA BREAKING NEWS and ARCHIVES)

Greetings:

For a break away from the politics, here is an interesting story about the amazing natural world of the creation. The more we learn, the more we realize we don't know anything, yet, really.... Chew on this Dawkins!

Decisions, decisions.

Have you ever seen a plant seed look like it's thinking? Researchers have found two small groups of cells inside plant embryos that operate in a similar way to the human brain, and help decide when the plant should start sprouting.

We're not talking about actual grey matter here, but the layout is similar to a human brain, with hormones moving between the two sets of cells in the same way that they do when we're deciding whether or not to move.


The team from the University of Birmingham in the UK used a maths model to show that communication between the two cell groups – one promoting dormancy and one promoting germination – controls the plant's sensitivity to its environment.
