Bio Lab Practical Study Guide Exam
Questions With Correct Answers
Organize the steps of the scientific method - correct answer<✔✔💖💖Observation/Question
Hypothesis
Experiment
Conclusion
Dependent Variable - correct answer<✔✔💖💖The variable measured. Y- axis
Independent Variable - correct answer<✔✔💖💖What could be manipulated and it's what affects
the dependent variable
Controlled Variable - correct answer<✔✔💖💖Held at a certain level. Serves as a benchmark, to
determine if the predicted effect was really due to the independent variable
Advantages of a compound microscope - correct answer<✔✔💖💖Can see smaller organisms in
high resolving power
Limitations of a compound microscope - correct answer<✔✔💖💖Only see 2D of organism
Advantages of a dissecting microscope - correct answer<✔✔💖💖Good for dissecting larger
organisms and viewing in 3D
Limitations of a dissecting microscope - correct answer<✔✔💖💖Low resolving power
If looking through the compound microscope using the 4x objective lens, what is the total
magnification? - correct answer<✔✔💖💖4= objective
, 10= ocular
4*10= 40
Know the parts of a microscope - correct answer<✔✔💖💖
What is cell type of a cheek cell? - correct answer<✔✔💖💖Multicellular
Cell Theory - correct answer<✔✔💖💖All living things are made of cells.
Cells are the basic units of structure and function in living things.
Living cells come only from other living cells.
Diffusion - correct answer<✔✔💖💖Molecules move from areas of high concentration to low
concentration without the need for any energy input
In the experiment with the dialysis tubing, which substances were able to move across the membrane
and which direction did they move? - correct answer<✔✔💖💖Starch ----> stayed put
Glucose----> moved out of tube and into beaker
I2KI-----> moved out of beaker and into bag
After one hour a potato, in a solution, gained 3% of its weight. What solution was it in? - correct
answer<✔✔💖💖Hypotonic
What is one similarity and one difference between diffusion and osmosis and why are they important to
cells? - correct answer<✔✔💖💖Osmosis = the diffusion of water across a semi-permeable
membrane
Diffusion- Spontaneous movement of particles from an area of high concentration to an area of low
concentration
Osmosis- Water moves from solution with lower concentration of dissolved particles to solution with
higher concentration of dissolved particles
