what size is a prokayotic cell
small
big
what is (A)
cell wall
nucleus
cell membrane
chloroplast
what is F
mitichondria
nucleus
chloroplast
vacole
which cell does not have a cell wall?
plant cell
animal cell
what is the function of a nucleus
supplie support and protection
traps energy from the sun
holds DNA for the cell
which formula do you use for this question:
A microscope has a field diameter of 180um when the mag is 100X. calculate the new FD for 400X mag
New FD= old FD X old total mag
-----------------------------
new total mag
est. FD
----
number of cells
that fit across the FD
total mag= ocular lens X objective lens
what formula would you use to estimate the cell size?
new FD= old FD X old total mag
-------------------------------
new total mag
est cell size= FD
-----
nuber of cells
which mesuerment has been converted from (mm) to (um) correctly
3.5mm=350um
3.5mm=35um
3.5mm=35000um
3.5mm=3500um
what is the function of the chloroplast
holds DNA for cell
traps energy from the sun
supplies support and protection
