Ch. 11.1 PRACTICE Flashcard

Front

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

Back

It decreases.

Front

Why does a larger cell find it more difficult to maintain normal functions?

Back

Because it struggles to move enough nutrients and wastes across its cell membrane.

Front

What is the key factor that determines the rate of nutrient and waste exchange in a cell?

Back

Surface area to volume ratio.

Front

What is the origin of all existing cells?

Back

All existing cells are produced by other living cells.

Front

What determines the amount of nutrients a cell needs?

Back

The cell's volume.

Front

Define surface area in the context of a cell.

Back

The total area of the cell membrane that is exposed to the environment.

Front

Define volume in the context of a cell.

Back

The amount of space the cell occupies.

Front

Explain why a high surface area to volume ratio is beneficial for cells.

Back

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

Front

What is the relationship between cell size and metabolic activity?

Back

As cell size increases, metabolic activity may decrease due to reduced efficiency in nutrient and waste exchange.

Front

What role does the cell membrane play in nutrient and waste exchange?

Back

It regulates the movement of substances in and out of the cell.
