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 ...

Unicellular and multicellular organisms must control their metabolism in order to survive. Metabolic rates can vary depending on physiological states. The circulatory system and respiratory system ...

Although some lineages or clades are entirely unicellular or multicellular (e.g., lobose amoeba and the land plants, respectively), most contain a mixture of body plans such as the unicellular and ...

The first life forms to appear on Earth were unicellular, i.e., composed of a single cell, such as yeast or bacteria. Later, ...

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.

How does this mutation in a unicellular organism affect the population compared to multicellular organisms? If one of your cells contain genes that mutates, this doesn’t make a big difference because ...

“Our findings show that the genetic underpinnings of cell-to-cell cohesion and segregation—the ability for different cells to sort themselves into separate regions within a multicellular mass—existed ...

Prokaryotes are unicellular and lack a nucleus and membrane-bound organelles. They are generally smaller and simpler and include bacteria and archaea. Eukaryotes on the other hand are often ...

Rice University bioengineers have developed a new construction kit for building custom sense-and-respond circuits in human cells. The research, published in the journal Science, represents a major ...

Macroalgae live in both fresh and seawater and are complex multicellular organisms with distinct organs and tissues, in ...
