Passive and Active Transport

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

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

What does semi-permeable mean?

• Some molecules can move through the membrane

• Nothing can move through the membrane

• All molecules can pass through the membrane.

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

Which form of active transport is being shown?

• Pinocytosis
• Endocytosis
• Exocytosis
• Osmosis

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

What happens to a cell placed in a HYPOTONIC solution?

• It shrinks
• It swells
• Nothing Happens

What happens to a cell placed in a HYPERTONIC solution

• It shrinks
• It swells
• Nothing happens

Which of the following is a job of the cell membrane?

• Regulates which materials enter and leave the cell.
• Breaks apart lipids, carbohydrates, and proteins from foods.
• Stores water, salt, proteins, and carbohydrates.
• Keeps the cell wall in place.

Particles of dye, when placed in a beaker of water, eventually spread evenly throughout the water. This is an example of

• isotonic

• diffusion

• osmosis

• active transport
