Front

The larger a cell is, the more difficult it is for the cell to move enough nutrients and wastes across its cell membrane to maintain its normal functions. True or False?

Back

True

Front

A small cell has a ________ surface area to volume ratio than a larger cell.

Back

larger

Front

High Surface area to volume ratio allows cells to do what quickly?

Back

Move materials in and out of the cell

Front

Define Surface area.

Back

The total area on the surface of an object

Front

What is the relationship between cell size and surface area to volume ratio?

Back

As cell size increases, the surface area to volume ratio decreases.

Front

Why is a high surface area to volume ratio beneficial for cells?

Back

It allows for more efficient exchange of materials with the environment.

Front

What happens to a cell's efficiency as it increases in size?

Back

It decreases due to a lower surface area to volume ratio.

Front

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

Back

6 x (length x width) for each face.

Front

What is the significance of the cell membrane in relation to cell size?

Back

It regulates the movement of nutrients and wastes in and out of the cell.
