Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy. It includes processes like diffusion, osmosis, and facilitated diffusion.

Front

What are the types of passive transport?

Back

The types of passive transport include diffusion, osmosis, facilitated diffusion, and ion channels.

Front

What is active transport?

Back

Active transport is the movement of molecules against their concentration gradient, requiring energy (ATP).

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration until equilibrium is reached.

Front

What is osmosis?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses carrier proteins to help move large or polar molecules across the cell membrane.

Front

What is equilibrium in the context of cell transport?

Back

Equilibrium is the state reached when the concentration of molecules is equal on both sides of a membrane, resulting in no net movement of molecules.

What happens to a plant cell in a hypotonic solution?

Back

When a plant cell is placed in a hypotonic solution, water enters the cell, causing it to swell and increase turgor pressure.

Front

What is turgor pressure?

Back

Turgor pressure is the pressure exerted by the fluid inside the central vacuole of a plant cell against the cell wall, helping maintain the cell's shape.
