No, growth is not taking place as there is no energy involved. only the process of endosmosis or imbibition is taking place which makes the gram to become bigger in size temporarily which do not require energy.

The seeds are not actually can say that they're refreshing themselves.

.gram seeds have proteins.when they're soaked in water due to imbibition they absorb water, their vacuoles fill completely with water.. because of this filling of vacuole it is clear that the vacuole will grow in will exert a pressure (turgor pressure) on the cell the vacuole is filled with water the seed grows in size but it doesn't mean it is literally germinating..This process is called DEPLASMOLYSIS..(when the vacuole exerts pressure on the cell wall the cell wall alse exerts a pressure on the cell contents called wall pressure)
