Front

What are the two main components of the cell membrane?

Back

Proteins and lipids.

Front

What is a primary function of the cell membrane?

Back

Regulates which materials enter and leave the cell.

Front

What are the functions of the nucleus?

Back

Controls most of the cell's processes, contains the information needed to make proteins, and stores DNA.

Front

Which type of cells contain a nucleus?

Back

Eukaryotes.

Front

What is the process called when a cell moves particles using energy against the concentration gradient?

Back

Active transport.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy, typically from high to low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What are organelles?

Back

Specialized structures within a cell that perform specific functions.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.
