Quiz #6 Active Transport, diffusion, osmosis, microscopes etc

What is passive transport?

• Movement of particles that requires energy from the cell

• Movement of particles from an area of lower concentration to an area of higher concentration

• Movement of particles from an area of higher concentration to an area of lower concentration

• Movement of materials against a concentration gradient

Which of the following is NOT an example of passive transport?

• Simple diffusion

• Facilitated diffusion

• Osmosis

• Endocytosis

What is osmosis?

• The movement of water across a selectively permeable membrane

• The movement of glucose across a cell membrane

• The movement of ions against their concentration gradient

• The process of engulfing large particles

In which direction do particles move during diffusion?

• From an area of lower concentration to an area of higher concentration

• From an area of higher concentration to an area of lower concentration

• Randomly in all directions regardless of concentration

• Against the concentration gradient

What happens to a cell placed in a hypotonic solution?

• The cell shrinks

• The cell maintains its normal shape

• The cell swells and could burst

• The cell divides

What is a characteristic of an isotonic solution?

• It has a higher solute concentration than inside the cell

• It has a lower solute concentration than inside the cell

• It has the same water and solute concentration as inside the cell

• It causes cells to burst immediately

What happens to a cell placed in a hypertonic solution?

• The cell swells

• The cell shrinks

• The cell maintains its normal shape

• The cell divides rapidly

Which process requires energy from the cell?

• Simple diffusion

• Osmosis

• Facilitated diffusion

• Active transport

What is facilitated diffusion?

• Movement of materials against a concentration gradient

• Passive transport of materials across the membrane using transport proteins

• The process of taking in material from the environment

• The expulsion of materials from a cell

What is the process called when a cell surrounds and takes in material from its environment?

• Exocytosis

• Endocytosis

• Osmosis

• Facilitated diffusion
