AP Bio Insta-Review Topic 2.3*: Cell Size

Front

What is the formula for the surface area of a sphere?

Back

The surface area of a sphere is given by the formula: 4πr², where r is the radius.

Front

What is the formula for the volume of a sphere?

Back

The volume of a sphere is given by the formula: (4/3)πr³, where r is the radius.

Front

What is the relationship between surface area and volume as cell size increases?

Back

As cell size increases, surface area increases with the square of the radius, while volume increases with the cube of the radius.

Front

Why is a smaller cell more efficient than a larger cell?

Back

Smaller cells have a higher surface area-to-volume ratio, allowing for more efficient nutrient uptake and waste removal.

Front

What is the formula for the surface area of a cube?

Back

The surface area of a cube is given by the formula: 6a², where a is the length of a side.

Front

What is the formula for the volume of a cube?

Back

The volume of a cube is given by the formula: a³, where a is the length of a side.

Front

How does the folding of the inner membrane of mitochondria benefit the cell?

Back

The folding increases the surface area available for oxidative phosphorylation, enhancing ATP production.

Front

What is the significance of the surface area-to-volume ratio in cells?

Back

A higher surface area-to-volume ratio allows for more efficient exchange of materials with the environment.

Front
