Cell Organelles, Cell Membrane, and Cell Transport

Front

What is the primary function of ribosomes in a cell?

Back

Ribosomes synthesize proteins that will be used by the cell.

Front

What process do cells use to move large particles out of the cell?

Back

Exocytosis.

Front

What is the role of the Golgi body in a cell?

Back

The Golgi body packages and modifies proteins.

Front

Define selective permeability in the context of cell membranes.

Back

Selective permeability is the property of the cell membrane that allows only some substances to enter and exit the cell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to move items such as glucose through the membrane.

Front

What are the two main types of cell transport?

Back

Passive transport and active transport.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

Name a type of active transport and describe it.

Back

One type of active transport is the sodium-potassium pump, which moves sodium ions out of the cell and potassium ions into the cell against their concentration gradients.

Front

What is the function of the cell membrane?

Back

The cell membrane protects the cell, provides structure, and regulates what enters and exits the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.
