Entering and Leaving the Cell

Gases move between the blood and the cells, moving from high concentration to low concentration.

• Osmosis

• Diffusion

• Facilitated diffusion

• homeostasis

What do we call it when particles are taken into the cell changing shape and engulfing the particles?

The cell uses energy to bring in sodium ions and pump out potassium ions.

Water diffuses across the cell membrane.

• passive transport

• active transport

• osmosis

• diffusion

Proteins aid the movement of materials through the cell membrane with no energy.

Although molecules move randomly in all directions during diffusion, usually they move? 

• low concentration to high concentration

• high concentration to low concentration

• stays the same

• no movement of molecules

Any type of movement across the cell membrane in which the cell does not use energy.

What do we call the movement of materials across the cell membrane using cellular energy?

What are the two kinds of active transport?

• diffusion

• exocytosis

• endocytosis

• osmosis

Some substances can pass through while other can not.
