Exploring Surface Area to Volume Ratio in Cells

What does a cell require from the outside world to sustain its activities?

• Light

• Sound

• Electricity

• Resources

What is expelled by the cell as a result of its internal activities?

• Water vapor

• Nutrients

• Oxygen

• Waste products

What happens to the surface area to volume ratio as a cell's volume increases?

• It remains constant

• It doubles

• It increases

• It decreases

For a spherical cell, what is the relationship between the radius and the surface area to volume ratio?

• Directly proportional

• Inversely proportional

• Unrelated

• Equal to the radius

What mathematical expression represents the surface area to volume ratio for a cuboidal cell?

• 6/x

• 6x^2

• x/6

• x^2

Why might larger cells struggle to exist?

• They are more likely to be eaten

• Insufficient surface area for exchange

• They require more food

• They can't move as easily

Which shape of cell is mentioned as having a surface area to volume ratio that decreases as its size increases?

• Cylindrical

• All of the above

• Spherical

• Cuboidal

How can cells increase their surface area to volume ratio?

• By becoming spherical

• By developing folds in their membrane

• By increasing their volume

What is a common adaptation seen in cells requiring high surface area to volume ratio?

• Membrane thickening

• Membrane folding

• Decrease in cell size

• Increase in cell volume

What is the result of a cell having a high surface area to volume ratio?

• Reduced cellular activity

• Increased water retention

• Enhanced exchange of resources and waste

• Increased energy production
