Cell Transport Review

Diffusion is the movement of a substance

• through a lipid bilayer

• only in water

• from an area of low concentration to an area of high concentration

• from an area of high concentration to an area of low concentration

The diffusion of water through a permeable membrane is called

• facilitated diffusion

• active transport

• osmosis

• endocytosis

Molecules that are too large to be moved through the cell membrane can be transported OUT OF the cell by

• osmosis

• exocytosis

• endocytosis

• diffusion

Which movement of substances through a cell membrane against a concentration gradient requires energy?

• osmosis

• diffusion

• active transport

• facilitated diffusion

Some molecules can move through the membrane while others cannot.

• Fully Permeable

• Selective Permeable

• Impermeable

• Partially Permeable

The movement of molecules from an area of higher concentration to an area of lower concentration is called

• diffusion
• exocytosis
• equlibrium
• active transport

This picture represents which type of cellular transport?

• passive transport
• endocytosis
• exocytosis
• osmosis

Osmosis is the movement of _____ across a membrane.
