Passive transport requires ________________

• concentration gradients

• no energy

• motion

• energy

Permeable means

• things can pass through

• the concentration levels are different

• it is permanent

• things are stuck

If there is 5 percent water inside a cell and 5 percent water outside a cell

• more water will move inside the cell

• more water will move outside the cell

• There will be no movement of water cells
