Cell Transport

Front

What is cell transport?

Back

Cell transport refers to the movement of substances across the cell membrane, which can occur through passive or active mechanisms.

Front

Define passive transport.

Back

Passive transport is the movement of molecules across the cell membrane without the use of energy, typically along the concentration gradient.

Front

What is active transport?

Back

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

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What role does the cell membrane play in transport?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is turgor pressure?

Back

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