Q
Adhesion
A
Attraction of water molecules to other kinds of molecules
22
Q
Surface tension
A
Cohesiveness of water results in this
23
Q
Capillarity
A
Properties of adhesion and cohesion result in this
24
Heat of vaporization
The energy required to break hydrogen bonding, allowing water to become a gas
25
Density
Mass per unit of volume
26
When is water most dense
4 degrees Celsius
27
Why does ice float
H20 at 0 degrees Celsius is less dense than liquid h20

Cohesion
Interactions with other water molecules or itself
30
Polar molecule
Opposite charges on the same molecule
31
Cell theory
All living organisms are made up of one or more cells, and all cells are derived from pre-existing cells.
32
Photosynthesis
CO2 + H20 + light energy = C6H12O6 + O2
33
Cell wall
Gives cell it's shape. Plant cells
34
Isotonic
A cell that has the same concentration if dissolved material inside the cell as outside the cell
35
Cytoplasmic streaming
Cyclosis
| Moment of cytoplasm in cell
36
Chloroplasts
Absorb sunlight
| Use it in photosynthesis
37
Saline solution
Has the same concentration of dissolved materials as the cell you are observing
38
Hypotonic
More dissolved materials in the cell,
Water into cell
Swell up, burst
39
Hypertonic
More dissolved materials outside of the cell
Water out of cell
Shrink
40
Osmosis
Movement of water across a selectively permeable membrane such as a plasma membrane
