Multiple Choice

The picture is an example of...

• active tranport
• passive transport
• diffusion
• osmosis

Multiple Choice

Which one is the definition of active transport?

• movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.

• passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane

• net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient

• net movement of molecule from a region of lower concentration to region of higher concentration. Molecule down a concentration gradient

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

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Multiple Choice

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Multiple Choice

When does diffusion stop?

• After a day and a night

• When the particles are evenly spread out

• When there are no particles left

• When all the particles leave the system

Multiple Choice

How do the particles move in diffusion?

• From a region of low concentration to a region of high concentration

• From a region of high concentration to a region of low concentration

• From a region of low concentration to a region of low concentration

• From a region of high concentration to a region of high concentration

Multiple Choice

Diffusion occurs only in solids

• True

• False
