Cell Size

Front

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

Back

As a cell increases in size, its volume grows faster than its surface area, leading to a lower surface area to volume ratio, which can hinder nutrient and waste exchange.

Front

How can surface area (SA) be increased?

Back

By dividing into smaller pieces.

Front

True or False: 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.

Back

True.

Front

True or False: It is better for a cell to have more membrane folds in order to exchange materials with the outside environment.

Back

True.

Front

Define Surface Area.

Back

The total area on the surface of an object.

Front

What does a high surface area to volume ratio allow cells to do quickly?

Back

Move materials in and out of the cell.

Front

What is the significance of membrane folds in cells?

Back

Membrane folds increase the surface area, enhancing the cell's ability to exchange materials.

Front

Why is it important for cells to maintain a high surface area to volume ratio?

Back

A high ratio facilitates efficient nutrient uptake and waste removal.

Front

What happens to a cell's efficiency as it grows larger?

Back

Its efficiency decreases due to the reduced surface area to volume ratio.

Front

What is one way cells adapt to maintain efficiency despite size?

Back

By developing specialized structures like microvilli to increase surface area.
