Unit 2 BiologyOnline version Quiz on Osmosis, by A Meyer 1 The Methylene blue diffused in the water. What does this mean? a High concentration to low concentration b high concentration to high concentration c low concentration to high concentration d low concentration to low concentration 2 Why does your whole room smell like air freshener if you only spray the air freshener in one location? a The molecules diffuse from the source throughout the space. b They won't move around unless you spray air freshener all over the room. c The molecules go from spread out to very densely packed, which is when you smell them. d A fan is required to push the air molecules around. 3 The dotted line in the middle acts more or less like a cell membrane. Molecules can pass through, but only those that can fit will pass through. What is the term that applies to membranes that describes that allows only some substances can pass through? a Semipermiable b Permiable c impermiable d phospholipid 4 What is required in PASSIVE transport (like diffusion)? a Does not require energy; goes with the gradient b requires energy; goes against gradient c requires energy; goes with gradient d doesn't require energy; goes against gradient 5 How is FACILITATED diffusion different from simple diffusion? a Facilitated requires a protein channel b no difference, diff terms for same thing c fascil. goes against gradient; simple goes with gradient 6 Passive transport requires energy to move molecules across membrane. a True b False 7 What happens to rate of diffusion with temperature? a Temperature doesn't affect the rate of diffusion b The higher the temperature, the faster the rate of diffusion c The lower the temperature, the faster the rate of dffusion d The higher the temperature, the slower the rate of dffusion 8 How does distance affect the rate of diffusion? a Smaller distance = faster rate b smaller distance = slower rate c distance doesn't affect rate d farther distance = faster rate 9 What type of molecules can pass the membrane easier? a Small, non polar molecules b small, polar molecules c large, non polar molecules d large, polar molecules 10 How does the mass of a molecule affect the rate of diffusion? a Lighter the molecule, the slower the rate of diffusion b The lighter the molecule, the faster the rate of diffusion c Mass doesn't affect the rate of diffusion d The heavier the molecule, the faster the rate of diffusion 11 Passive Transport is called passive transport because it does not require... a Energy b proteins 12 What is passive transport? Written answer 13 What is a solute? Written answer 14 Where would water travel, in Osmosis, among two sides? a Side A: High water concentration, low solute concentration b Side B: low water concentration, high solute concentration 15 If you dump salt in one side, where would water go? a Non-salt side: Side A b Salt side: Side B 16 What is it called when there is higher solute concentration? a Hypertonic b Hypotonic c Isotonic 17 What is it when there is LOW solute concentration? a Hypertonic b Hypotonic c Isotonic 18 Hypo rhymes with ____, hypotonic means ___ solute concentration Written answer 19 What comes from Hypotonic liquid? a Shrinking b Swelling c It stays stable 20 What comes from Hypertonic liquid? a Shrinking b Swelling c It stays stable 21 What comes from Isotonic liquid? a Shrinking b Swelling c It stays stable 22 Of equal concentration a Isotonic b Hypertonic c Hypotonic 23 What does mitosis NOT do? a Make sex cells b Help an organism grow c produce body cells d heal cuts and wounds 24 What does mitosis include? a Sex cells b body cells 25 cells made from mitosis are identical a true b false 26 Cancer is.. a mitosis b cell division c uncontrolled cell growth 27 Cells spend most time in mitosis a true b false 28 What are chromosomes made of? Choose one or more answers a Genes b DNA c Proteins d DNA and Proteins Feedback 9 Small, nonpolar substances such as Oxygen and Carbon Dioxide can diffuse across the membrane (so doesn't require energy, a channel, and goes with the concentration). 14 Water will go towards high solute 27 Actually is interphase
