Where is a plant's "brain"? You know how plants lean into the sun- What does that!?

Question

I have a withering plant, so I set it on my balcony for 3 hours of sun. In those 3 hours, it completely spread out and changed its form - I know plants tend to lean into the light, but whats the driving force behind this decision? What, if any, would constitute a plant's 'thinking' portion? Just curious. Also, any tips on keeping plants indoors would be appreciated!! Mine keep dying, and its just confirming my fears that one day I'll make a terrible father and come home to decaying people. Thnx!

Answer 1

There's something certain: plants have no brain. What you mean it is produced by hormones and it is a property of the plants so called "fototropism".

Answer 2

There is no 'plant brain'. It turn out that the part of a step that is darker grows slightly faster that the part that exposed to sunlight. That is what causes the plant to bend towards the sunlight.
