When considering singular entities, the largest organisms are clonal colonies which can spread over large areas.

The largest individual flower in the world is ''Rafflesia arnoldii'', while the flowering plant with the largest unbranched inflorescence in the world is ''Amorphophallus titanum.'' Both are native to Sumatra in Indonesia.
===Green algae=== Green algae are photosynthetic unicellular and multicellular "green plants" that are related to land plants. The thallus of the unicellular mermaid's wineglass, ''Acetabularia'', can grow to several inches (perhaps 0.1 to 0.2 m) in length. The fronds of the similarly unicellular ''Caulerpa taxifolia'' can grow up to a foot (0.3 m) long.{{Citation needed|date=January 2021}}
