AP Daily Video Questions (Answer here):

1.  What are the components of an effective graph
mentioned in the video? Title, labeled axes with units, scaling, identifiable lines or bars, trend line

2.  Describe the most common use for each of the following
types of graphs:
- Line graph: tracks changes over time, trends or progresses
- Scatterplot: to determine relationship between two things
- Histogram: show how values in data set are distributed across evenly spaced intervals
- Bar graph: compare multiple groups or treatments to each other
- Box and whisker plot: show variability in the sample
- Dual Y: illustrate relationships between two independent variables

3.  What types of graphs are used in the practice problems
in this video? Bar graph, line garph

AP Daily Video Questions (Answer here)
1.  What does water potential measure? measures the tendency of water to move by osmosis

2.  What are the two components of water potential? water and solute potential

3.  Water moves from areas of _____high______ water potential to areas of __lower______ water potential.

4.  The value of water potential can be ___positive____, _____0____, or ____negative______.

5.  What is the water potential of pure water? 0

Read & take notes and label drawings (when necessary) in your AP Biology notebook.

As you read, answer the following:

1. Describe the source of energy for active transport (the molecule and what happens to it).

2. Why is active transport said to be directional?

3. Describe endocytosis in general, then each type specifically: (Study Fig. 5.8 carefully)
a) Phagocytosis

b) pinocytosis

c) receptor-mediated endocytosis (Review Fig. 5.9 carefully)

4. What happens during exocytosis?

a) Give examples of different substances secreted by exocytosis.

AP Daily Video 2.8 Tonicity and Osmoregulation

1.  What is osmosis?  The diffusion of free water across a selectively permeable membrane

2.  Water is a polar molecule, so how do large quantities of
water get across the phospholipid bilayer? Water moves by osmosis and has high solvency abilities

3.  Explain the difference between a solute and a solvent. A solute is the substance being dissolved, a solvent is a substance that dissolves a solute

4.  The total solute concentration in a solution is called
__osmolarity_________________

5.  What is tonicity? The measurement of relative concentrations of solute between two solutions

6.  How are water concentrations and solute concentrations
related to each other? They are inversely related because water moves frmo an hypotonic environment

7.  Water diffuses from a ______hypotonic___________ environment into a
______________hypertonic ________ environment.

8.  Explain how water moves in a dynamic equilibrium. Equal amounts of water move in and out of the cell at equal rates

9.  In plant cells, environmental hypertonicity results in
________less cellular solute____________, which results in water
______plasmolysis_______________  the cell.

10.  In plant cells, environmental hypotonicity results in
_______more cellular solute ______________, which results in water
_______plasmolysis _____________  the cell.

11.  Explain why a plant cell does not lyse/explode when in
environmental hypotonicity. Osmotic pressure

12.  In animal cells, environmental hypertonicity results in a
cell that is ___shriveled__________.

13.  In animal cells, environmental hypotonicity results in a
cell that is ___lysed __________

14.  How does a paramecium avoid lysis in a hypotonic
environment? excess water collects in the vacuole and the pumped out
