This organelle consists of a series of flattened membrane sacs called cisternae and is responsible for protein trafficking.
What is the (Golgi Complex)?
100
These cells have a higher SA:V ratio, making them more efficient at exchanging materials.
What are small cells?
100
This model describes the cell membrane as a tapestry of moving phospholipids, proteins, and carbohydrates.
What is Fluid Mosaic Model?
100
These small, nonpolar molecules can pass freely through the phospholipid bilayer without help. (N2, O2, or CO2) via .................. transport
What is diffusion/passive?
100
In this type of solution, there is no net movement of water into or out of the cell.
What is Isotonic?
200
This organelle contains hydrolytic enzymes used for intracellular digestion and apoptosis.
What is the Lysosome?
200
According to the formula, if a cube's side length doubles, its SA:V ratio is cut by this much.
What is "in half"?
200
Fungi cell walls and arthropod's exoeskeletons are made of this carbohydrate, which differs from plants
What is chitin?
200
This process uses energy to move molecules against their concentration gradient.
What is Active Transport?
200
A cell placed in this type of solution will shrivel as water leaves.
What is Hypertonic?
300
In plants, this large organelle provides turgor pressure and stores water/waste.
What is the Central Vacuole?
300
These openings in leaves allow for gas exchange while balancing water loss
What are stomata?
300
This steroid molecule helps maintain membrane fluidity at different temperatures.
What is Cholesterol
300
This process involves the cell membrane folding inward to take in large macromolecules.
What is Endocytosis?
300
Pure water has a water potential value of this.
What is zero?
400
This organelle contains thylakoids and stroma for capturing light energy.
What is the Chloroplast?
400
Cells use this "folded" strategy to increase surface area without greatly increasing volume.
What are Membrane folding/Convolutions?
400
These "fingerprint" molecules on the membrane surface are important for cell-to-cell recognition.
What are Glycoproteins or Glycolipids?
400
This specific pump maintains the membrane potential in nerve cells by moving 3 Na+ out and 2 K+ in.
What is Na+/K+ pump/ATPase?
400
Adding solute to a solution always ______ the water potential.
What is Lowers/Decrease?
500
- This theory explains why mitochondria and chloroplasts have double membranes and their own DNA.
What is the Endosymbiotic Theory?
500
When a cell's volume gets too large, this becomes the "limiting factor" for its survival.
What is Diffusion rate/or Exchange of gases?
500
This property allows the membrane to regulate what enters and leaves the cell.
What is Selective Permeability?
500
When a membrane has a difference in charge across it, it is said to be this.
What is Polarized?
500
These organelles in protists like Paramecium pump out excess water to maintain homeostasis.
What are Contractile Vacuoles?
600
Identify two structural pieces of evidence that support the claim that mitochondria were once free-living prokaryotes.
What are... Double membranes, their own circular DNA, or their own ribosomes (70s).

A plant cell with a solute potential of -4.0 bars is placed in an open beaker of 0.2M sucrose solution at 27°C. Calculate the water potential of the solution and predict the direction of water flow. (i=1, R=0.0831).
The Answer: What is... Solution bars; water flows OUT of the cell (from -4.0 to -4.98).
Use the formula: 
(Ionization constant): Since sucrose is a sugar, it does not ionize in water. 
.
(Molar concentration): Given as 0.2
(Pressure constant): Given as 0.0831
(Temperature in Kelvin): 27+273
The Calculation:-1*0.2*).0831*300K=4.98
