Scientist holding a model of a thale cress (Arabidopsis thaliana) embryo root tip. Cells in the embryonic root tip are responsible for deciding when the seed germinates. This decision is key: germinating too early can mean the plant must survive harsh winter conditions, too late and the plant may be outcompeted by plants that germinated earlier.
