Reference entries modular organism in A Dictionary of Ecology 4 Length: 68 words. Two sets composed of two plants each were observed. The sun-loving plants, Alternanthera and Cyperus and the shade-tolerated plants, Zebrina and Talinum, are used as experimental species of each categories of plant environment.

Althernanthera reaches a height of 5 to 15 inches and grows lowly. Alternanthera needs plenty of light to grow and form dark leaves. In open aquariums it grows willingly up the surface, and like other difficult plants growth improves considerably if CO2 is added Cyperus is a species of sedge native to Africa, southern and central Europe and southern Asia.

It is a perennial plant that may reach a height of up to 40 cm. It is argued here that bacteria are essentially modular organisms where the bacterial cell, microcolony, and macrocolony are modules of different levels of complexity analogous to modules of macroorganisms.

This interpretation provides a broad conceptual basis for understanding the natural history of bacteria, and may illuminate the evolutionary origins and developmental biology of modular creatures. Abstract The body plan of modular organisms is based on an indeterminate structure composed of iterated units or modules arrayed at various levels of complexity such as leaves, twigs, and branches.
