electron microscopes were invented in

• 1960's

• 1930's

• 1950's

• 1940's

electron microscopes give much greater detail of

• sub cellular structures

• cellular structures

• pre cellular structures

• base cellular structures

electron microscopes give much greater detail of sub cellular structures with in a

• genetic code

• cell

• blood cell

• neucleus

electron microscopes give much greater detail of sub cellular structures with in a cell

but the sample being observed must be

• soft

• hard

• alive

• dead

there are two types of electron microscopes

• input electron microscope

• scanning electron microscope

• visual electron microscope

• micro electron microscope

• transmission electron microscope

scanning electron microscopes produce

• 3 dimensional images

• 2 dimensional images

• 4 dimensional images

• 1 dimensional images

scanning electron microscopes produce 3 dimensional images at a

• the same magnification

• higher magnification

• lower magnification

• better resolution

transmission electron microscopes produce

• 1 dimensional images

• 4 dimensional images

• 2 dimensional images

• 3 dimensional images

transmission electron microscopes produce 2 dimensional images with

• different magnification

• high magnification

• low magnification

• the same magnification

transmission electron microscopes produce 2 dimensional images with high magnification and

• visual

• quality

• resolution

• imagery
