Mixotrophic and heterotrophic protists hold a key position in aquatic microbial food webs. Whereas they can account for the bulk of bacterivory in pelagic systems, the potential structuring effect of ...

Flagella and cilia are used in unicellular and multicellular eukaryotes for fast cell motility, rapid movement of material over cell surfaces, cell feeding and cell division. The structure of the ...

Across all species, directed movement is essential for nutrient acquisition, energy harvesting, and the avoidance of danger or sources of stress. Organisms have evolved specific means of locomotion ...

Flagella are composed of over 20 unique proteins and represent a complex set of molecular machinery, working in unison to provide motility to many Gram-negative and positive species of bacteria, as ...
