It is Sphagnum, which is mosses in bryophytes.In the leaf of the gametophyte, there is hyaline cells which are dead cells. Hyaline cell can retain water wall and release water slowly.They can store water up to 25 times of their dry weight. therefore it is used as the plant material for sanitary pads. Also there are photosynthetic cells in the leaf, they are long narrow and green in colour. In the stem of the gametophyte, there are thin wall call in the centre, thick wall cell in the pheriphery and large thin wall cortex. Also, there are no rhizoid in the mature stage.
