Cell Transport

Front

What is homeostasis in the context of cell transport?

Back

Homeostasis is the state of stable internal and external conditions in a cell, allowing it to function optimally.

Front

What type of solution has a greater solute concentration inside the cell?

Back

A hypotonic solution has a greater solute concentration inside the cell, causing water to move into the cell.

Front

What is diffusion in the context of cell transport?

Back

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

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What does it mean for a cell to be in an isotonic solution?

Back

In an isotonic solution, water moves in and out of the cell equally, maintaining cell size and shape.

Front

What is the role of the cell membrane in transport?

Back

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

Front

What is osmosis?

Back

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

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is the difference between facilitated diffusion and simple diffusion?

Back

Facilitated diffusion requires specific transport proteins to help move substances across the membrane, while simple diffusion does not.
