Chapter 3 Section 2

Diffusion is one type of active transport.

• True

• False

What a cell membrane is because it allows only certain substances to enter and leave a cell

• permanent
• plasma
• semipermeable
• flex wall

The movement of substances through a cell membrane without using the cells energy

• Massive transport

• inactive transport

• automatic transport

• passive transport

• passing transport

Movement of substances from an area of higher concentration to an area of lower concentration

• Endocytosis

• Exocytosis

• diffusion

• fusion

• abusion

When the concentration of molecules is the same on both sides of a membrane

• equilibrium

• diffusion

• osmosis

• active transport

• passive transport

The diffusion of water molecules only through a membrane

• diffusion

• endocytosis

• exocytosis

• passive transport

• osmosis

A cell membrane that allows certain things to pass into and out of a cell

• permeable

• semipermeable

• selective

• closed

• open

When molecules pass through a cell membrane using special proteins call transport proteins

• Diffusion

• osmosis

• facilitated diffusion

• active transport

• assisted diffusion

The movement of substances through a cell membrane only by using energy

• passive transport

• inactive transport

• active transport

• facilitated transport

• energy transport

Type of transport where molecules move from areas of high concentration to areas of low concentrations

• massive

• active

• passing

• passive

• easy
