Plasmodium falciparum is a one-celled organism that causes a severe form of malaria. Distinction of Plasmodium falciparum from other malaria causing Plasmodia can be made by seeing, under the microscope, its gametocyte (sexual form) that is characteristically shaped like a banana – banana-shaped gametocyte.
