Is malaria multicellular?
Malaria is a disease - it isn't an organism. However, the protozoan that causes malaria is unicellular.
Plasmodium, from the genus plasmodium, as in those organisms which cause Malaria are unicellular organisms. Plasmodium, as in part of the life cycle of a slim mold, can be either acellular, in which multiple nuclei are encased by a single membrane, making them "unicellular" or they can be cellular, in which they have multiple cells and in a way are "multicellular." So they techincally can be both depending on the type of slim mold.
