Diplobacilli (diplo-bacilli): This is the name given to rod-shaped bacteria that remain in pairs following cell division. They divide by binary fission and are joined end to end.

Diplobacteria (diplo-bacteria): Diplobacteria is the general term for bacteria cells that are joined in pairs.

Diplobiont (diplo-biont): A diplobiont is an organism, such as a plant or fungus, that has both haploid and diploid generations in its life cyle.

Diploblastic (diplo-blastic): This term refers to organisms that have body tissues that are derived from two germ layers: the endoderm and ectoderm. Examples include cnidarians: jellyfish, sea anemones, and hydras.

Diplocardia (diplo-cardia): Diplocardia is a condition in which the right and left halves of the heart are separated by a fissure or groove.

Diplocardiac (diplo-cardiac): Mammals and birds are examples of diplocardiac organisms. They have two separate circulatory pathways for blood: pulmonary and systemic circuits.
