Practice Test: Cell Transport

The movement of any molecule from an area of high concentration to low concentration is

• osmosis
• diffusion
• active transport
• endocytosis

The movement of WATER from an area of high concentration to low concentration is 

• osmosis
• diffusion
• active transport
• endocytosis

The movement of molecules across a cell membrane from high concentration to low concentration that DOES NOT require energy is

• osmosis
• active transport
• passive transport
• endocytosis

The purpose of passive transport (diffusion and osmosis) is

• to reach equilibrium
• to reach the point where there is more of something in a cell
• to make sure there is not a balance of molecules
• to reach a balance of the environment only outside of the cell

The cell membrane only allows some substances to pass through. That means that the cell membrane is

• semipermeable (selectively permeable)
• is a border that doesn't allow things to pass through
• a structure that acts like a wall
• is really mean

The pumping of molecules from an area of LOW concentration to HIGH concentration USING ENERGY is an example of

• osmosis
• diffusion
• exocytosis
• active transport

When a large object enters a cell by wrapping part of its membrane around it and engulfing it is an example of active transport called

• diffusion
• osmosis
• endocytosis
• exocytosis

When a large particle(s) exit a cell, it requires energy so it is a form of active transport called

• endocytosis
• exocytosis
• active transport
• passive transport

Where is there a higher concentration of water?

• outside the cell
• inside the cell

In what direction will the water flow?

• Out of the cell from high to low concentration
• Into the cell from high to low concentration
• Out of the cell from low to high concentration
• Into the cell from low to high concentration
