What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules pass through a cell membrane using transport proteins, allowing substances to move from areas of high concentration to low concentration without using energy.

What is the function of the nucleus in a cell?

Back

The nucleus directs all cell activities and contains the cell's DNA, which carries genetic information.

Front

What is cellular respiration?

Back

Cellular respiration is a series of chemical reactions that convert energy in food molecules into ATP, which cells use for energy.

Front

What is the cell wall?

Back

The cell wall is a stiff structure located outside the cell membrane that provides support and protection to the cell.

Front

What is active transport?

Back

Active transport is the movement of substances through a cell membrane using the cell's energy, allowing substances to move against their concentration gradient.

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration without the use of energy.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What are transport proteins?

Back

Transport proteins are proteins that help move substances across a cell membrane, either by facilitated diffusion or active transport.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is the cytoplasm?

Back

Cytoplasm is the jelly-like substance inside a cell that contains all the organelles and is where many cellular processes occur.
