Question 1

what are prokaryotic cells?

Answer 1

organisms that lack a nucleus

Question 2

what are some features of a prokaryote?

Answer 2

average length is about 0.1-5.0 micrometers
bacterial flagellum
nucleoid
pili
cell wall
plasma membrane
single circular chromosome

Question 3

what is binary fission?

Answer 3

when prokaryotic cells split themselves from one cell into two

Question 4

what is the process of binary fission?

Answer 4

the cell makes copies of its internal components
the cell then splits in half
creates an identical copy of the original cell

Question 5

what are eukaryotic cells?

Answer 5

cells that contain a nucleus

Question 6

what are some features of a eukaryote?

Answer 6

large in size around 10-100 micrometers
nucleus
cell membrane
plant cells have a cell wall
rough and smooth endoplasmic reticulum
Golgi apparatus
lysosome

Question 7

why is an electron microscope better?

Answer 7

has a higher resolution compared to a light microscope

Question 8

what does the transition electron microscope do?

Answer 8

shoots electrons through the specimen to generate an image

Question 9

what does the scanning electron microscope do?

Answer 9

electrons bounce off pf the specimen to generate a three-dimensional structure

Question 10

what is a negative effect of the electron microscope?

Answer 10

there is a loss of any natural colour or stain
