Cell Transport

Front

What is cell transport?

Back

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

Front

What are the two main types of cell transport?

Back

Passive transport and active transport.

Front

What is passive transport?

Back

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

Front

What is active transport?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses proteins to help move substances across the cell membrane without energy.

Front

What does homeostasis mean in the context of cell transport?

Back

Homeostasis refers to the maintenance of a stable internal environment within a cell, despite changes in external conditions.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane, moving from an area of lower solute concentration to an area of higher solute concentration.

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 enter the cell.

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 leave the cell.

Front

What is isotonic solution?

Back

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