Biology Active and Passive Transport Review

Movement of molecules from an area of high concentration to an area of low concentration is

• diffusion 
• passive transport
• osmosis
• all of the above

Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• Active Transport

Movement of molecules through the cell membrane from high to low concentration

• passive transport

• active transport

Active transport moves substances against a concentration gradient 

• true
• false 

Which form of active transport is being shown?

• Pinocytosis
• Endocytosis
• Exocytosis
• Osmosis

When cells take in food molecules through active transport, what is it called?

• diffusion

• phagocytosis

• exocytosis

• osmosis

When cells form a vesicle to release materials, which form of transport is occurring? 

• Endocytosis
• Exocytosis
• Facilitated Diffusion
• Osmosis

Materials that can move across a membrane with passive transport include

• water, oxygen, and carbon dioxide
• starch and other polysaccharides
• DNA and RNA
• large proteins

When the concentration of solute molecules outside the cell is equal to the concentration inside the cell, the solution is

• hypertonic
• hypotonic
• isotonic
• ionic

What happens to a cell placed in a HYPOTONIC solution?

• It shrinks
• It swells
• Nothing Happens
