Surface Area and Volume Ratios

Does the rate at which materials diffuse into a cell vary with the size of the cell?

• No, it remains constant regardless of size.

• Yes, because larger cells have a higher diffusion rate.

• Yes, because when it is too large, it cannot reach the center of the cell.

• No, smaller cells have a slower diffusion rate.

What does a large cell size mean for the rate of diffusion?

• The rate of diffusion is faster.

• The rate of diffusion is slower.

• The rate of diffusion is unaffected.

• The rate of diffusion is the same as smaller cells.

What is the relationship between surface area and volume ratio as the size of a cube increases?

• The ratio increases.

• The ratio decreases.

• The ratio remains constant.

• The ratio doubles.

Why is the surface area to volume ratio important for cells?

• It determines the color of the cell.

• It affects the rate of diffusion of materials.

• It controls the cell's temperature.

• It influences the cell's shape.

What happens to the surface area to volume ratio when the side of a cube is much less than one?

• The ratio becomes very large.

• The ratio becomes very small.

• The ratio remains unchanged.

• The ratio becomes zero.
