plasmids, slime capsule, membrane, cellwall, flagella, dna
11 of 25
Are bacteria cells unicellular or multicellular
unicellular
12 of 25
How do yeast cells reproduce
asexually- the new cells buddding off
13 of 25
Revise functuions of cells (hw) and which cells have what start of 9x1 book 1
not a flash card

What is the function of ribosomes where are they found and what do they look like?
where protein's made ,look like little dots, found in cytoplasm
15 of 25
What is the function of mitrochondria where are they found and what do they look like?
where respiration happens(releases glucose and energy) look like long ovals,found in the cytoplasm
16 of 25
which types of cells have the most mitrochondria?
liver cells , muscle cells, sperm cells
17 of 25
which is more exspensive light microscope or electron microscope
electron microscope
18 of 25
which needs a longer exposure light or electron microscope
light microscope
19 of 25
light microscope
long exposure, quick camera shutter- sample needs to be still, stain sample, need thin sample- no alive specimines
20 of 25
electron microscope
electrons hit sample bounce back to create image, no camera need like light microscope, sample on disk,focuses it's self- less man work, more expensive than ligh microscope, quick prep. time, it can disinguish 2 objects that close together
21 of 25
what is magnification
to the degree to which the size of the image is lager than the object itself
22 of 25
revise cm,mm,um,nm conversions 9x1 first book near start 9/9/16
revise it!
23 of 25
how do you get overall magnification?
eyepiece magnification X objective magnification = overall magnification
24 of 25
things to remember in scientific drawing
draw in pencil, labels, not too detailes, no shading, NO art pencil, no overlapping, unfinishes or shakey lines, sharp pencil, draw specimine in rectangle, write total magnification
