Diffusion, Osmosis, and Active Transport

Which transport does not require energy?

• Passive
• Active 

What is Osmosis?

• equal concentration
• diffusion of water through a selectively-permeable membrane
• high to low concentration
• non-polar tail

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

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Controlling what goes into or out of the cell with the help of energy is called

• active transport
• endocytosis
• passive transport
• exocytosis

Which of the following substances passes through the plasma membrane   through the process of osmosis?

• glucose
• water
• protein
• sodium

Which of the following does not have a cell wall?

• animal cells
• bacteria cells
• plant cells
• fungi

The movement of atoms, ions, or molecules from an area of high concentration to an area of low concentration.

• osmosis
• active transport
• diffusion
• hypertonic

A state of biological balance

• homeostasis
• turgor pressure
• hypotonic
• plasma membrane

During osmosis

• water moves from high to low concentration
• water moves from low to high
• water moves when energy is used
• proteins are built
