AP Biology Unit 2 Review part 1

Front

What is a major cause of the size limits for certain types of cells?

Back

The need for sufficient surface area to support the cell's metabolic needs.

Front

How can you determine if a cell is eukaryotic?

Back

They have membrane bound organelles.

Front

Define a eukaryotic cell.

Back

A cell containing a nucleus and other membrane bound organelles.

Front

What does it mean for plasma membranes to be selectively permeable?

Back

The membrane regulates the passage of the material in and out of the cell.

Front

What type of molecules do cells with large numbers of ribosomes specialize in producing?

Back

Proteins.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What are membrane-bound organelles?

Back

Organelles that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the role of the plasma membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

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

Back

A higher surface area to volume ratio allows for more efficient exchange of materials.
