Pleomorphism (Noun)

(biology) the appearance of two or more distinctly different forms in the life cycle of some organisms.

Nouns denoting natural phenomena.

The parasite exhibited pleomorphism throughout its life cycle, displaying multiple distinct forms in different hosts.
Pleomorphism in the protozoan parasite allowed it to evade the host's immune system by continually changing its morphological appearance.
Studies on the life cycle of certain fungi have revealed remarkable examples of pleomorphism, with drastic changes occurring between spores and mature organisms.
The species of bacteria in question demonstrated pleomorphism, transforming from a motile, spiral shape to a dormant, cyst-like form under stress conditions.
Understanding the mechanisms underlying pleomorphism in certain parasites is crucial for the development of effective treatments against the diseases they cause.

(chemistry) the existence of different kinds of crystal of the same chemical compound.

Nouns denoting natural phenomena.

Pleomorphism in chemistry refers to the coexistence of different crystal structures of the same compound, often resulting in varying physical properties.
Pleomorphism is commonly observed in solid-state compounds where the same chemical formula can exhibit different crystal arrangements.
The study of pleomorphism provides valuable insights into the structural diversity of chemical compounds and its implications on their physical and chemical properties.
Silicon dioxide, for example, exhibits pleomorphism as it can form crystalline structures such as quartz and cristobalite, each with distinct physical characteristics.
Understanding pleomorphism is essential in materials science as it can influence the electrical, optical, and mechanical properties of crystalline compounds.
