How do cells take in large particles?

Back

Endocytosis

Front

What does 'selectively permeable' mean?

Back

It means that the membrane allows certain substances to pass while blocking others.

What is the hydrophobic region of the cell membrane?

Back

The part of the membrane that repels water, typically made of fatty acid tails.

Front

What is the process called when water diffuses across a membrane?

Back

Osmosis

Front

What are the two main types of transport across cell membranes?

Back

Passive transport and active transport.

Front

What is passive transport?

Back

Movement of substances across a cell membrane without the use of energy.

Front

What is active transport?

Back

Movement of substances against their concentration gradient, requiring energy.

Front

What is the role of proteins in the cell membrane?

Back

Proteins help with transport, communication, and structural support.

Front

What is the function of carbohydrates in the cell membrane?

Back

Carbohydrates are involved in cell recognition and signaling.
