AP BIOLOGY UNIT 2 TOPIC 2.3 Cell Size Quiz

Why is cell size important in biological systems?

• To affect the efficiency of nutrient and waste exchange, as well as the ability to support cellular functions.

• To increase the number of organelles

• To improve the color of the cell

• To make the cell look bigger

Explain how cell size can affect the efficiency of cellular processes.

• Larger cells are more efficient than smaller cells

• Cell size can affect the efficiency of cellular processes by impacting the rate of diffusion of molecules and the surface area to volume ratio.

• Cell size has no impact on the efficiency of cellular processes

• Cell size only affects the color of the cell

What are the factors that can affect the size of a cell?

• Availability of nutrients, rate of waste removal, and surface area to volume ratio

• Color of the cell

• Distance from the equator

• Number of organelles in the cell

How does the environment influence the size of a cell?

• By determining the shape of the cell

• By regulating the temperature of the cell

• By providing the necessary nutrients and conditions for growth.

• By controlling the genetic makeup of the cell

Describe the concept of surface area to volume ratio in relation to cell size.

• Surface area to length ratio describes the relationship between the surface area and length of a cell.

• Surface area to volume ratio describes the relationship between the surface area and volume of a cell.

• Surface area to density ratio describes the relationship between the surface area and density of a cell.

• Surface area to weight ratio describes the relationship between the surface area and weight of a cell.

How does the surface area to volume ratio impact the functioning of a cell?

• It changes the genetic makeup of the cell

• It has no impact on the functioning of a cell

• It causes the cell to produce more energy

• It affects the rate of exchange of materials with the environment.

How does cell size affect the rate of diffusion within the cell?

• The rate of diffusion decreases as cell size increases.

• Cell size has no effect on the rate of diffusion.

• The rate of diffusion increases as cell size increases.

• The rate of diffusion is not related to cell size.

Explain the relationship between cell size and the ability of substances to diffuse into and out of the cell.

• Cell size has no effect on the ability of substances to diffuse into and out of the cell.

• As cell size increases, the ability of substances to diffuse into and out of the cell increases.

• The relationship between cell size and the ability of substances to diffuse into and out of the cell is random.

• As cell size increases, the ability of substances to diffuse into and out of the cell decreases.

How does cell size impact the metabolic activity of a cell?

• Smaller cells have a lower surface area to volume ratio, leading to less efficient nutrient exchange.

• Cell size has no impact on the metabolic activity of a cell.

• Larger cells have a higher surface area to volume ratio, leading to more efficient nutrient exchange.

• Smaller cells have a higher surface area to volume ratio, leading to more efficient nutrient exchange.

Discuss the relationship between cell size and the energy requirements of a cell.

• Cell size has no impact on the energy requirements of the cell.

• As cell size increases, the energy requirements of the cell also increase.

• As cell size increases, the energy requirements of the cell decrease.

• Smaller cells require more energy than larger cells.
