Homeostasis and Transport Review FB

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

How does a cell maintain homeostasis?

• Regulates what enters and leaves the cell
• Flexibility
• Protective barrier
• Structure and support

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 carrier protein?

• Diffusion
• Osmosis
• Active Transport
• Facilitated Diffusion

When molecules are spread evenly across the cell membrane, ______________________ is reached.

• difference
• transportation
• equilibrium
• solution

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 

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck
