1. Serologic
Used to accurately dispense volumes of liquids
al Pipette
2. pasteur pipette Used to dispense liquids when accuracy is less important , and to
gently mix liquid mixtures by pipetting in and out
3. Preparing wet To spread a sample thin enough ( between a glass slide and a glass cove
mounts on slip) to view clearly under a microscope
glass slides
4. A simple To determine whether a sample contains starch
chemi-
cal test : Using Io- Starch= plant/veggies
dine to test No starch = animals
for starch
5. Cheesecloth Used to filter out larger solids while allowing liquids and smaller particles
and funnel eg.
filter in- Cells, organelles, etc) to pass through
structions
6. how do active/facilitated transport, selective permeability of lipid bilayer, and
mole- cules concentra- tion gradient
pass the
membrane
Used to view objects at 40x 100x or 400x magnification - to see cells
7. compound
mi- croscope
8. spectrophotome- Used to measure how much light ( of each specific wavelength/colour
is ab-
ter

rbed by a sample. A prism is across a wider range of possible wavelengths
used to split the light, so
that you can test one Used to separate the particles within a mixture into layers according to their
wavelength at a time relative densities, by spinning the mixture at extremely high speeds. The
densest particles are found at the bottom of the table

10. Independen The variable that is manipulated and its ettect on the dependent variable is
t variable measured
11. Hypertonic When the concentration of solute is greater outside than inside, water flows
out= causes cell to shrivel and shrink in size
12. Hypotonic When the concentration of solute is greater inside the cell than outside,
water
flows in= causes cell to swell and burst
13. isotonic when the concentration of both the solute and solvent is equal so theres n
net
movement
14. What solution
happens
when you put 17. the cell mem- brane is perme- able to
a cell into a
18. the cell mem- brane is not per- meable to
hypo- tonic
solution?
15. what happens
when you put
a cell into a
hyper- tonic
solution

happens
when you put
a cell into an
iso- tonic
