Sentences with phrase «celled eukaryotic organisms»

The genus Cryptosporidium, a group of single - celled eukaryotic organisms in the phylum Apicomplexa, comprises an unknown number of species infecting numerous vertebrate species.

A Snowball to Acidic Hothouse swing would have greatly added to already high evolutionary pressures from anaerobic extinctions through genetic isolation of selective survival adaptations and may have led singled - celled eukaryotic organisms to cooperate together physically and form the first multi-cellular lifeforms.

Not exact matches

The consensus on the evolution of primitive life is that simple life forms (prokaryotes, organisms whose cells lack a distinct nucleus) inhabited the Earth about 3 - 4 billion years ago, eukaryotic cells (those with a nucleus which contains the genetic material) emerging 2 - 3 billion years ago.

Cells with nuclei, called eukaryotic cells (which make up virtually all multi-cellular organisms) are much larger and more complex that prokaryotic cells and likely resulted from the early combining of prokaryotic cCells with nuclei, called eukaryotic cells (which make up virtually all multi-cellular organisms) are much larger and more complex that prokaryotic cells and likely resulted from the early combining of prokaryotic ccells (which make up virtually all multi-cellular organisms) are much larger and more complex that prokaryotic cells and likely resulted from the early combining of prokaryotic ccells and likely resulted from the early combining of prokaryotic cellscells.

A fungus (plural fungi) is a eukaryotic organism that digests its food externally and absorbs the nutrient molecules into its cells.

The advent of the nucleus — which differentiates eukaryotes (organisms whose cells contain a true nucleus), including humans, from prokaryotes, such as bacteria — can not be satisfactorily explained solely by the gradual adaptation of prokaryotic cells until they became eukaryotic.

The living world thrived long before the origin of nucleated organisms [the eukaryotic cells, which have genetic material enclosed in well - defined membranes].

Prokaryotic cells are usually singletons, while eukaryotic cells are usually found in multi-cellular organisms.

It is the first synthetic chromosome ever assembled from a eukaryotic organism, the type in which cells store DNA in nuclei.

It allows eukaryotic cells to evolve into multicellular organisms that have remarkable structural and functional variation.

In fact, as with eukaryotic organisms, division of Caulobacter cells generates two different daughter cells, which can be easily separated.

Contained within all eukaryotic cells, mitochondria possess their own DNA due to their evolutionary history as an «enslaved» bacterium swallowed up billions of years ago by a primitive eukaryotic organism.

We could fairly posit that the evolutionary origin of the eukaryotic cell was «the first time that what went around came around», a quid pro quo with among primitive organisms in deep time.

Such series of cell fate transitions of stem cells ultimately lead to the development of a higher eukaryotic organism.

The CellDevo Track focuses on the study of molecular mechanisms in eukaryotic cells and their role in tissue formation, with the level of analysis ranging from single molecules to single cells, from cells to tissues, and from tissues to whole organisms.

(All multi-cell organisms are made of eukaryotic cells; the other type of cell, prokaryotic, is found in single - cell organisms.)

These newly identified organisms might have a big impact on our understanding of the deeper branches of the tree of life giving us new hints about the emergence of the eukaryotic cell.

From seed and spore dispersal, to rapid cell growth of eukaryotic organisms, and the pulsing cilia needed to sustain them, to the slow growth of lichens and moss - life has a remarkable way of establishing itself on the planet; yet, most of these processes go unseen to the human eye.
