The movement of water across a selectively permeable membrane without the use of any energy is called

• endocytosis
• diffusion
• active transport
• osmosis

The picture is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Two examples of passive transport are

• Earth and Sun
• Diffusion and Osmosis
• Energy and Wind
• None of the above

What a cell needs to transport particles by active transport?

• Sun
• Wind
• Energy
• Channels

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium
