Bacteria Lecture ! Might as well learn about em, because you dirty kids are covered in them!

What you have to be able to do Describe the size of bacteria Describe where we find bacteria Describe a couple different types of bacteria Compare a virus to a bacteria Compare bacteria to eukaryota

Quick note Most bacteria are not harmful to humans!

Bacteria = prokaryotes Prokaryote  Before nucleus! Tiny! 1000x smaller than one of your cells Abundant in air water soil, your notebook, Logan’s phone, Sam’s locker creen&NR=1&v=JAqW4OTFB4M

Organization of a bacteria* Most have cell wall surrounding membrane Glycocalyx surrounds cell wall (it’s a polysaccharide Capsule vs slime layer Fimbrae

Binary Fission Technically different than mitosis Same result!

Bacteria link via a sex/ conjugation pilus DNA passes through pilus Conjugation

Transformation Prokaryotes pick up DNA in the environment

Bacteria types Gram positive – have peptidoglycan layer penicillin works against PG layer Gram negative - no peptidoglycan layer

Bacteria Types Spirilum Bacilli Coccus

Biochem Some live only without oxygen obligate anaerobes – Tetanus botulism, Facultative anaerobes

Autotrophic or heterotrophic Some make their food Some do not
