What happens during osmosis?

• water molecules moves from high to low concentration without the use of energy

• water molecules moves from high to low concentration with the use of energy

• water molecules moves from high to low water potential without the use of energy

• water molecules move from high to low water potential with the use of energy

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

• glucose
• water
• protein
• sodium

Plasma membranes are selectively permeable. This means

• anything can pass in and out

• the membrane regulates the passage of the material in and out of the cell

• Large molecules can enter the cell

• cholesterol cannot enter
