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 such as diffusion, osmosis, and active transport.

Front

What is pinocytosis?

Back

Pinocytosis is a type of endocytosis where the cell engulfs liquid substances from the surrounding environment.

Front

What is active transport?

Back

Active transport is the process of moving substances against their concentration gradient, requiring energy (usually in the form of ATP).

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a membrane.

Front

What is homeostasis?

Back

Homeostasis is the ability of a cell or organism to maintain a stable internal environment despite changes in external conditions.

Front

What happens to a cell in an isotonic solution?

Back

A cell in an isotonic solution will stay the same size because the concentration of solutes is equal inside and outside the cell.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

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

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their gradient.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane is a barrier that allows certain substances to pass while blocking others.
