Understanding Diffusion

What is the primary concept being introduced in the lesson?

• Evaporation

• Photosynthesis

• Diffusion

• Osmosis

In the deodorant demonstration, what term is used to describe the area with many particles?

• High concentration

• Medium concentration

• No concentration

• Low concentration

How is diffusion defined in the context of this lesson?

• Movement of particles from high to low concentration

• Movement of particles in a straight line

• Movement of particles from low to high concentration

• Movement of particles in a circular motion

What is a unicellular organism?

• An organism with multiple cells

• An organism with no cells

• An organism with one cell

• An organism with two cells

Why does oxygen continue to diffuse into a unicellular organism?

• Because the cell does not need oxygen

• Because the cell has a higher concentration of oxygen

• Because the cell has a lower concentration of oxygen

• Because the cell is impermeable to oxygen

What does 'multi' signify in multicellular organisms?

• One

• Two

• Many

• None

How is oxygen supplied to cells in multicellular organisms?

• By the blood

• Through the stomach

• Through the skin

• By the bones

What happens to oxygen once it diffuses into the cells?

• It is expelled immediately

• It is stored for later use

• It is used in respiration

• It remains unused

What ensures the continuous diffusion of oxygen into cells?

• Constant low concentration outside the cell

• Constant high concentration outside the cell

• Constant low concentration inside the cell

• Constant high concentration inside the cell

What is suggested for further understanding of diffusion?

• Listening to music

• Watching a movie

• Using a worksheet

• Reading a book
