Cell membrane and Transport

This is a picture of

• Cell wall
• Cell membrane
• chloroplast
• mitochondria

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.

A can of air freshener is sprayed in the opposite side of the room.  Ten minutes later you start to smell the scent.  This is an example of 

• diffusion
• active transport
• endocytosis
• osmosis

Controlling what goes into or out of the cell without energy is called

• active transport
• endocytosis
• passive transport
• exocytosis

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a transport protein?

• Diffusion
• Osmosis
• Active Transport
• Facilitated Diffusion

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 

Where is there a low concentration of dye?

• at the bottom of cup
• in the color
• at the top of cup 
• no concenteraion gradient
