Osmosis
#1 What does osmosis involve that diffusion doesn't? A membrane
#2 What kind of transport is osmosis? Passive Transport
#3 Which direction will water flow for a potato in salt water? Out of the potato
#4 Which way will water flow for an egg in a hypotonic solution? Into the egg
#5 Which direction will osmosis occur in for a cell and solution that are isotonic? No osmosis
Diffusion
#1 Diffusion is the process of material flowing from __________ to ___________ concentration. High to Low
#2 What effect does higher temperature have on diffusion? Speeds it up
#3 What could you do to speed up diffusion of a powdered drink mix through a water bottle? Shake it
#4 How much energy does diffusion consume? Zero
#5 What is the term describing how concentration levels change across a liquid? Concentration Gradient
Active Transport
#1 Which consumes more energy - endocytosis or osmosis? Endocytosis
#2 This is the term for a cell 'eating': Phagocytosis
#3 This term describes when a cell ejects waste: Exocytosis
#4 This is the term for when a cell 'drinks': Pinocytosis
#5 Phagocytosis and Pinocytosis are both examples of: Endocytosis
Passive Transport
#1 What are osmosis and diffusion both trying to achieve? Equilibrium
#2 This is the name for the substance dissolved within a liquid: Solute
#3 This is the name for a liquid that dissolves a substance: Solvent (Solution)
#4 In a hypertonic solution, what will happen to a cell? It will shrink
#5 What is the name used to describe a cell and solution that are at equilibrium? Isotonic
Miscellaneous
