Differences in archea and eu cells
lives in hot and acidic places
lives in salty places
Bacteria cells are smaller than _____ cells and bigger than a _____.
Bacteria shaped like a rod
Bacteria shaped like a squiggle
Bacteria shaped like circles
controls what comes in and out
some protection; maintains structure of cell
optional; primary protection from antibiotics
everything inside the cell; contains cytosol (liquid that everything floats around in)
help them attach; aids in exchanging plasmids
extra pieces of DNA; can contain genes for resistance, that create capsules
rare for most bacteria; for protection when bacteria is in an inhospitable environment
dark purple results, no capsule, can use antibiotics
light pink results, has a capsule, much tougher time finding an antibiotic
1. copy DNA 2. split in half
temperature, pressure, pH, salt concentration, space
Population is limited by... (five things)
Using a pili, two bacteria can trade plasmids (trade info) NOT part of reproduction!
helps you digest your food
First thing bacteria does for us: make ________.
Second thing bacteria does for us: breaks down ___.
Third thing bacteria does for us: makes ______.
foundation, food chains
Fourth thing bacteria does for us: provides __________ for many ____ ______.
bacteria that makes you sick
kill bacteria by preventing reproduction or punching holes in the cell wall
When were antibiotics first mass-produced and who discovered them?
look for the clear zone where no bacteria grow (zone of inhibition)
zone of inhibition
the clear zone where no bacteria grow
Some bacteria are lucky enough to have a natural mutation that allows them to survive in the presence of an antibiotic, they can pass this mutation to other bacteria either through normal reproduction or through conjugation
