principles of biology lab

base

the platform that rests on the table and supports the body of the microscope

arm

vertical frame of the microscope

stage

holds the slide

mechinical stage

moves the slide

ocular lenses

attached to the biocular head

revolving nosepiece 

holds several objective lenses 

iris

opens and closes the amount of light coming through

is the direction e the same when you are looking through the microscope as without

no it is not the same

does teh slide move in the direction you anticpiated 

no it moves in the opposite direction due to its inverted

prokaryotes

bacteria is a

domain archae 

found in extreme environments and acidic areas  

flagella

many bacteria have

flagella function

rotate like a propeller of a motor boat

pilli 

short hair like extensions used fro attachment to a surface 

bacteria cell wall

peptideogylcan and a capsule

aniamls don’t have

cell wall

euglena

single celled and use flagella

prokaryotes have 

chloroplast and central vacoule 

central vacoule

stroage and maintain pressure cho

cholorplast

photosynthesis

animal cells share common with 

protist and plants 

epitjrial cells

tissue that cover the body surfaces and organs and line the body cavity

protist can be

auto or hetero fun

fungi are

heterotrophic and both uni or multipl

plants are 

multi and eukaroyotic 

animals are

multi

bacteria cell wall is

peptioglycon

prokarytes haev threee shapes 

cocci, spiral, bacilli 

fungi function

decay for nurtrients and secrete enzymes outside cell

fungi have

yeast which are uni

fungi can be multi for example 

mushroom

fungal cell wall

chitin
