Microbe
short for microorganism which means small organism - observed with a microscope
99
% of microbes contribute to the quality of human life
Prions
Infectious agents composed primarily of protein which induce the existing polypeptides in host cells to take on its form.
Prokaryotic
single cell with nuclear material but no nuclear membrane or membrane bound organelles
Eukaryotic
most cells - with organized nucleus and membrane bound organelles
Mitochondria and Chloroplasts
have DNA similar to that of a Prokaryotic cell and can reproduce independent of the rest of the Eukaryotic cell
Bacteria
has only one cell, lives in all environments.
small minority
A _____ ________ of microbes cause disease in humans by sheer numbers or producing powerful toxins.
bacteria, Archaea, algae, fungi, protozoa, and viruses
major groups of microbes are:
Microbes
In terms of numbers, what represent most of the diversity of life on earth and are found in every environment?
Acellular
Viruses do not have cellular components, nor do they grow or metabolize organic materials. Generally consist of a piece of nucleic acid encased in protein which must use the cellular components of a living cell to reproduce.
Prions
proteinaceous infectious particles
Prions
infectious agents composed primarily of protein which induce the existing polypeptides in host cells to take on its form.

chemoautotrophic
bacteria that synthesize their own food using energy from chemical reations.
recycling in nitrogen and sulfur cycles
what are chemoautorphic bacteria important for?
flagella
What do some bacteria have that rotates like a tiny outboard motor?
slime like slugs
