Cell Transport

The movement of particles from an area of high to low concentration is known as--

• Passive Transport

• Active Transport

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

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion

How does a cell maintain homeostasis?

• By controlling what enters and leaves the cell

• Flexibility

• Protective barrier

• Structure and support

Cell membrane transport that occurs without energy is called--

• active transport

• endocytosis

• passive transport

• exocytosis

What is the name of the process in which small molecules move from an area of high concentration to an area of low concentration across the cell membrane

• 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 

The movement of molecules from low to high is known as

• simple diffusion

• facilitated diffusion

• active transport

• osmosis

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Which is true about active transport?

• It requires energy
• It does not require energy
• It moves substances down the concentration gradient
• it moves material from high to low concentration

Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• There is no water
