Front

What determines the absorption of nutrients in a cell?

Back

The cell's surface area.

Front

What determines the amount of nutrients needed by a cell?

Back

The cell's volume.

Front

What is the term for the amount of space something takes up?

Back

Volume.

Front

As a cell becomes larger, what happens to its surface area and volume?

Back

Volume increases faster than its surface area.

Front

What is the principle that states all existing cells are produced by other cells?

Back

Living cells.

Front

Define surface area in the context of cells.

Back

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

Front

Explain why a larger cell may have difficulty absorbing nutrients.

Back

Because as the cell grows, its volume increases faster than its surface area, making it harder to absorb nutrients efficiently.

Front

What role do ribosomes play in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the function of the Rough Endoplasmic Reticulum (Rough ER)?

Back

The Rough ER is involved in the synthesis and processing of proteins.

Front

What is the function of the Smooth Endoplasmic Reticulum (Smooth ER)?

Back

The Smooth ER is involved in lipid synthesis and detoxification.
