Understanding Cell Processes: Diffusion and Osmosis

What is the primary characteristic of diffusion in cells?

• Molecules move from low to high concentration

• Molecules move from high to low concentration

• Energy is required for molecules to move

• Water moves through a semi-permeable membrane

How does osmosis differ from regular diffusion?

• It specifically involves the movement of water

• It occurs only in plant cells

• It involves the movement of gases

• It requires energy input from the cell

What analogy is used to describe osmosis in the video?

• A scent spreading in a room

• A crowd entering a stadium

• A game of tag

• A river flowing downstream

Why are diffusion and osmosis crucial for cell survival?

• They prevent cells from dividing

• They enable cells to obtain nutrients and expel waste

• They allow cells to communicate with each other

• They help cells to produce energy

What role does osmosis play in a cell's water management?

• It ensures the cell does not overheat

• It allows the cell to store energy

• It helps the cell to produce proteins

• It prevents the cell from drowning or shriveling
