Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell ...

Mitochondria are very well known as the powerhouses of the cell. Generally speaking, all eukaryotes, including plants, fungi, and animals, are made of cells that contain mitochondria. These organelles ...

We counted a minimum of 15 protist cells per sample (62 cells on average). ... Table 1 A global view of microbial components (protists, prokaryotes and large viruses) in the deep ocean.

In their study, reported in Science, Flaum and Prakash investigated a particularly striking feature found in a protist named Lacrymaria olor. Measuring 40 µm in length, this shapeshifting organism ...

In new research published this week, a team led by Marine Biological Laboratory (MBL) scientists reveals that symbiotic bacteria often accompany single-celled protists in the ocean’s upper layer ...

Teeny, single-cell creatures floating in the ocean may be the first organisms ever confirmed to eat viruses. Scientists scooped up the organisms, known as protists, from the surface waters of the ...

But, when researchers looked at the genetic code, the protist Oligohymenophorea sp. PL0344 turned out to be a novel species with an unlikely change in how its DNA is translated into proteins.

Scientists used single-cell genomics to show that two groups of poorly known marine protists routinely ingest viruses. They hypothesize that this serves to absorb phosphorus and nitrogen - that is ...

Matz says the protists probably move by sending leg-like extensions, called pseudopodia, out of their cells in all directions. The pseudopodia then grab onto mud in one direction and the organism ...
