Prokaryotes
They are structurally simpler and smaller than eukaryotes
Prokaryotes
Their DNA (genetic material) is usually a single, circularly arranged chromosome and is not surounded by a membrane
Eukaryotes
their DNA is found in multiple chromosomes in a membrane-enclosed nucleus
Eukaryotic cells
Plants and animals are composed of what type of cells?
bacteria and archaea
The prokaryotes in the microbial world
fungi (yeasts and molds), protozoa, and algae
Cellular microbes that are eukaryotes
glycocalyx
This surrounds both eukaryotic and prokaryotic cells
most bacteria
in nature, these are found sticking to solid surfaces, including other cells, rather than free-floating
Glycocalyx
the glue that holds the cells in place
fimbriae
E. coli bacteria use this to attach to the urinary bladder, resulting in infection
Glycocalyx (yellow)
Serratia bacteria adhere to plastic using strands of this
nucleic acids, proteins, lipids, and carbohydrates
Prokaryotes and eukaryotes both contain these:
