Passive Active Transport

 An animal cell placed in a hypertonic (salty) solution will

• Stay the same

• Shrink- get smaller

• Swell- get bigger

Moving from areas of LOW concentration to areas of HIGH concentration is called?

• Passive Transport

• Active Transport

• Diffusion

• Osmosis

The process that moves materials through the cell membrane WITHOUT using energy.

• Passive Transport

• Active Transport

• Endocytosis

• Exocytosis

What is the difference between Active and Passive Transport? Active transport ​ (a)   . Passive transport ​ (b)   .

• uses energy

• does NOT use energy

• Diffusion

• Endocytosis

• Osmosis

• Exocytosis

The process that moves WATER molecules across a cell membrane.

• Diffusion

• Osmosis

• Endocytosis

• Exocytosis

Passive transport occurs when particles move from ​ (a)   to (b)   concentration.

• high

• low

• inside the cell

• outside the cell

• high energy

• low energy

An egg was placed in water overnight. The egg became larger. What caused this to happen?

• Diffusion of water into the yolk.

• Osmosis of water from beaker into the egg.

• Osmosis of water from out of the egg into the beaker.

• Diffusion caused equal amounts of water in the egg and beaker.
