Osmosis Lesson

Types of Cell Transport:

Osmosis

Multiple Choice

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Multiple Choice

Where is there a low concentration of perfume?

• in the bottle
• on the hand
• in the room
• in the top

Multiple Choice

Where is there a high concentration of water?

• in the flower
• cannot be determined by picture.
• in the vase
• in the leaves

Multiple Choice

How long does diffusion last?

• Until the concentration of particles in the system is equal

• Until a region in the system has a smaller concentration of particles than the other

• Until a region in the system has a greater concentration of particles than the other

• Until the particles disappear from the system

Multiple Choice

Where is there a low concentration of dye?

• at the bottom of cup
• in the color
• at the top of cup 
• no concenteraion gradient

Multiple Choice

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Multiple Choice

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm

Multiple Choice

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Multiple Choice

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Multiple Choice

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration 
  

Multiple Choice

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium

Multiple Choice

Ideally, your cells should be in a(n) _______ solution

• Hypertonic
• Hypotonic
• Isotonic
• Cola

Multiple Choice

An animal cell placed in a hypertonic (salty) solution will

• Shrink
• Swell
• Stay the same

Multiple Choice

Why can't you drink salt water?

• It's hypertonic to your cells

• It's hypotonic to your cells

• It's isotonic to your cells

• It's paratonic to your cells

Multiple Choice

If the dots represent sugar which is more concentrated

• Inside the cell

• Outside the cell

• Neither they are equal (equilibrium)

Multiple Choice

If the dots represent sugar, what direction will water flow?

• Into the cell

• Out of the cell

• Into and out equally (equilibrium)

Multiple Choice

A person should never drink salty water because their cells would

• shrink
• expand
