Y10 Diffusion, osmosis, active transport + respiration

Osmosis is the diffusion of _____ across a partially permeable membrane.

• food

• air

• water

• oxygen

What will happen if an animal cell is placed in a very salty solution?

• Stay the same

• Shrink- get smaller

• Swell- get bigger

In a solution, salt is considered the _______.

• solvent

• solute

• solution

The movement of molecules against a concentration gradient (using energy)

• simple diffusion

• osmosis

• active transport

Which part of the cell can control what goes in and out of the cell?

• Cell Membrane

• cell wall

• Mitochondria

• Cytoplasm

What is diffusion?

• when molecules move

• when molecules move randomly from a high concentration to a low concentration

• no movement

• molecules rush to fill every space

The picture below is an example of _________________.

• Sun

• Wind

• Energy

• Channels

The picture is an example of...

• active tranport
