Understanding Cellular Transport Processes

Cells sometimes use energy to transport materials across the cell membrane.  This is called

• Simple Diffusion

• osmosis

• Facilitated diffusion

• active transport

What is passive transport?

• The movement of molecules against a concentration gradient using energy.

• The movement of molecules across a cell membrane without using energy.

• The process of engulfing large particles into the cell.

• The release of substances from a cell.

What is osmosis?

• The movement of water molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

• The movement of solute particles from a region of higher concentration to a region of lower concentration.

• The process of a cell taking in large particles by engulfing them.

• The release of waste materials from a cell.

Which process involves the movement of molecules from an area of high concentration to an area of low concentration?

• Endocytosis

• Exocytosis

• Diffusion

• Active transport

What is endocytosis?

• The process of a cell releasing substances to the outside environment.

• The movement of water molecules through a membrane.

• The process of a cell taking in substances by engulfing them.

• The movement of molecules without energy.
