The phospholipid bilayer

• A

The membrane is often described as

• the organelle that controls what goes in and out of the cell

• a fluid mosaic phospholipid bilayer

• selectively permeable

• all of these

The permeability of the membrane to a substance seems to primarily depend on...

• the kind of substance it is chemically

• how much of the substance is present

• the size of the molecules of the substance

• the temperature of the environment

The picture is an example of...

• active tranport
• passive transport
• diffusion
• osmosis

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not
