A device (1) for transplanting plants (P) including a plant carrier (6,7,8,9) having a plurality of cells (C) for plants with root plugs arranged in parallel rows, an extraction arrangement for successively extracting the plants (P) from the cells (C), and a planting tool (5) for subsequent planting the extracted plants. The extraction arrangement includes a bottom support structure for covering cell bottoms and for supporting each root plug, and the bottom support structure includes a first plate (10) and a second plate (11) which are movable relative to each other and to the plant carrier (6,7,8,9) to successively open the bottom of the cells (C) thereby allowing the plants (P) to be extracted downwards, one by one, root plug first, towards the planting tool (5).
