The study is published in the journal Nature. The first life forms to appear on Earth were unicellular, i.e., composed of a single cell, such as yeast or bacteria. Later, animals—multicellular ...

A single bacterium consists of just one cell. Not all bacteria are harmful. There are different unicellular organisms and types of bacteria. Yeast are unicellular fungi. They are used by brewers ...

The unicellular ancestor of animals may have harbored some of the molecular tools that its many-celled descendants use to coordinate and direct cell differentiation and function, scientists show.

The study is based on the fluid dynamics of cooperative feeding by Stentor, a relatively giant unicellular organism. Humans like to think that being multicellular (and bigger) is a definite ...

Unicellular organisms, such as microalgae, also age when they can no longer divide due to a lack of nutrients. The newly discovered mechanism enables old cells to rejuvenate and divide again after ...

Solid black circles indicate major lineages composed entirely of unicellular species. Other groups shown contain only multicellular species (solid red), some multicellular and some unicellular ...

How does multicellularity evolve? Scientists who study a family of green algae that includes unicellular Chlamydomonas and multicellular Volvox are beginning to find answers to this question.

A single bacterium consists of just one cell. Not all bacteria are harmful. There are different unicellular organisms and types of bacteria. Yeast are unicellular fungi. They are used by brewers ...
