What type of transport occurs when solutes move with the concentration gradient without using energy?

Back

Passive Transport.

Front

What type of transport uses ATP (energy) to move substances across the cell membrane?

Back

Active Transport.

Front

What is the primary function of chloroplasts in plant cells?

Back

Photosynthesis.

Front

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

Back

Facilitated Diffusion.

Front

Define 'Diffusion'.

Back

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

Front

What is 'Osmosis'?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular activities.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What is a selectively permeable membrane?

Back

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