The microscope
Give a real world analogy to the cell membrane
Security guard
Name two of the three parts of the cell theory
1. All organisms are composed of one or more cells
2. The cell is the basic unit of structure and function in organisms
3. New cells are produced from existing cells
Name the organelle whose function is to make proteins and is may located on the ER
Explain the difference between simple diffusion and facilitated diffusion.
In facilitated diffusion the particle is typically charged and large. A channel protein aids in the diffusion. Whereas simple diffusion the particles can pass freely and are uncharged. No assistance requried.
This scientists coined the term "the cell" by observing pieces of cork in the microscope

Eu - skin cells
Pro - Bacteria
Define aquaporin
A specific protein channel for water
Name the organelle whose function is the following -"Fluid filled, stores waste"
Vacuole
Endocytosis is the process of taking material into the cell.
Tell me an example of what phagocytosis is
or what pinocytosis is
phagocytosis - "cell eating" it is consuming food

Anton van Leeuwenhoek discovered bacteria by observing the gunk on his teeth. At the time he name them... what?
"Animalules" because they looked like tiny animals
Give me three characteristics of a prokaryotic cell
or a eukaryotic cell
Eu - large, complex, multicellular, nucleus, membrane bound organelles
Pro - small, simple, typically unicellular, no nucleus, no membrane bound organelles
Define osmotic pressue
Different solute concentrations inside and outside the cell can lead to a net loss or a net gain of water
Name the organelle whose function is the following -
"Provides support, structure, and shape for the cell"
Cytoskeleton
If a an egg is placed in a jar full of syrup, what would happen? (I am looking for specific terms here)
Osmosis will occur. Since the solution is hypertonic, the egg will expel water. This causes a net loss of water and the egg will shrink

Schleidan - botany (plants)
Virchow - animals
