Homeostasis and Transport Practice

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is facilitated diffusion?

Back

A process that allows substances to cross membranes with the assistance of special proteins.

Front

What is the role of transport proteins in the cell membrane?

Back

Transport proteins help large molecules pass through the cell membrane.

Front

What is homeostasis?

Back

The process of maintaining internal balance within a cell or organism.

Front

What is osmosis?

Back

The movement of water molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion refers to the movement of solute particles, while osmosis specifically refers to the movement of water.

Front

What is exocytosis?

Back

The process by which a cell expels materials in vesicles that fuse with the cell membrane.

Front

What is endocytosis?

Back

The process by which a cell takes in materials by engulfing them in a vesicle.

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.
