Bacteria- Procaryotes (pp) - Coggle Diagram
Bacteria- Procaryotes (pp)
evolved to live in almost any kind of environment
extreme acidity
3.2 km below earth
extremely salty conditions
Biomass of bacteria is 10x greater than the biomass of all Eukaryotes combined
How Bacteria make you sick
They can produce toxins
They can crowd your cells & take their resources
use your cells’ nutrients to live & reproduced
Extracellular Bacteria
do NOT actually enter your cells
their toxins still make you sick
Examples:
E. coil
Streptococcus
Staphylococcus
Intracellular Bacteria
Actually live inside your cells
Bacteria reproduce inside of cells & cells are killed in the process
Examples:
Chlamydia
Listeria
The most abundant organisms on earth
Most bacterial cell walls are made out of a substance called peptidoglycan
Capsule
outside of their cell wall that allows them to stick to surfaces or each other
prevent cell dehydration
Can protect from the immune system
Ways Bacteria Can Become Resistant to Antibiotics:
Some have developed an enzymes that can break down antibiotics before they can take effect
Some have started producing a capsule that is resistant to antibiotics
Some have changed the shape of their Penicillin Binding Proteins
Some have developed ways to make their cell membranes less permeable to antibiotics.
