Solution:

In Plasmodium life cycle, when metacryptozoite enters into an erythrocyte , it becomes a rounded young trophozoite. As it grows, a large non contractile vacuole appears in its centre in its centre, pushing the cytoplasm and nucleus to a thin peripheral layer to give a signet-ring appearance to the trophozoite.
