Movement of molecules across a cell membrane without the usage of energy.
Active Transport
Passive Transport
Cellular Transport
Molecular Transport
Movement of water from high to low concentrations across a semi-permeable membrane.
Osmosis
Diffusion
Endocytosis
Exocytosis
Movement of larger molecules across a cell membrane using a transport protein; molecules still move from high to low concentration
Osmosis
Active Transport
Facilitated Diffusion
Hypertonicity
Higher solute concentration inside the cell than outside, water moves IN to the cell causing it to swell
Isotonic
Hypertonic
Hypotonic
Megatonic
Higher solute concentration outside the cell than inside the cell, water moves OUT and the cell shrinks
Hypertonic
Isotonic
Hypotonic
Cytotonic
Solute concentration is equal inside and outside the cell, water moves IN and OUT evenly. Cell remains the same size.
Hypertonic
Hypotonic
Isotonic
Oligotonic
An equal concentration of molecules inside and outside of the cell
Equilibrium
Hypertonic
Hypotonic
Diffusion
Movement of molecules from high to low concentration towards equilibrium
Osmosis
Active Transport
Mitosis
Diffusion
The amount of a substance (solute) within a specific volume of solution.
Concentration
Tonicity
Osmosis
Meiosis
This picture shows what type of macromolecule?

Unpermeability
Which of the following is a function of the cell membrane?
breaks down lipids, carbohydrates, and proteins from foods
stores water, salt, proteins, and carbohydrates
synthesizes proteins and other macromolecules
regulates the movement of materials into and out of the cell
Term used to describes the arrangement of the cell membrane as bendable (like a fluid) and made of many parts (like a puzzle).
A phospholipid has two parts. What are they called?
Hydrophilic Head, Hydrophobic Tail

Most lipids contain _____, however, these are not true monomers.
amino acids
monosaccharides
nucleotides
glycerol and fatty acids
Lipids functions to
build and break down other molecules
store energy long term
create hormones
store genetic information
Active transport is movement of particles through the cell membrane from a region of ...1... to a region of ...2... using energy in the form of ...3...
1: lower concentration, 2: higher concentration, 3: NADPH
1: higher concentration, 2: lower concentration, 3: NADPH
1: higher concentration, 2: lower concentration, 3: ATP
1: lower concentration, 2: higher concentration, 3: ATP
Which is an accurate description of the diagram below?
Na+ and Amino Acids are both transporting passively.
Na+ and Amino Acids are both transporting actively.
Na+ is diffusing passively, and Amino Acids are transporting actively.
Na+ is transporting actively, and Amino Acids are diffusing passively.
What might happen if a cell did not have any ATP/energy?
It would not have enough energy to do active transport
It's cell membrane would break
The transport proteins would not be needed.
Water is considered the universal _______ because it can dissolve most things if left in it.
Solute
Solution
Hydrator
Solvent
Water can hold large amounts of heat compared to other compounds. Ex: Can help keep water warm and keep costal areas stable in temperature
Heat of Vaporization/ Thermoregulation
High Specific Heat/Heat Storage
Solvent Ability
Cohesion
When water absorbs enough heat it evaporates, resulting in a cooling effect. Example: Sweat.
High Specific Heat
Adhesion
Cohesion
Thermoregulation / Vaporization
When water freezes, its solid form (ice) is less dense than water, so it floats. This allows a layer of ice to form on top of ponds, keeping the water a stable temperature and allowing fish and plants to survive the winter.
Adhesion
Heat of Vaporization
Density (Ice Formation)
Solvent
Water's ability to bond to other water molecules. Example: Surface Tension
Cohesion
Adhesion
Covalent
Evaporative Cooling
Water's ability to bond to other molecules. Example: Water sticking to grass or glass.
Adhesion
Cohesion
Covalent
Condensation
A weak bond that uses polarity to hold water molecules close to other water molecules.
Covalent Bond
Hydrogen Bond
Ionic Bond
Systemic Bond
A water molecule is considered ________ because the electrons are shared unevenly, resulting in a slightly positive and negative side.
Non-Polar
Polar
Covalent
Metallic
A uniform mixture of solute + solvent. Example: Kool-Aid
Solvent
Solute
Solution
Heterozygous
What IS dissolved in a solution. Example: Salt, Sugar, or Kool-Aid Powder
Solvent
Solute
Solution
Hypotonic
Quantitative data relies on ___________________________.
descriptions.
numbers.
colors.
noise.
