Cell Organelles & Cell Transport Review

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, causing water to move out of cells, leading to cell shrinkage.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

What are the two parts of a phospholipid?

Back

Hydrophilic Head and Hydrophobic Tail.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through 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 the process of passive transport of molecules across a cell membrane via a protein channel.

Front

What role do vacuoles play in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is the sodium-potassium pump?

Back

The sodium-potassium pump is a type of active transport that moves sodium ions out of the cell and potassium ions into the cell, crucial for maintaining cellular function.

Front

What is isotonic solution?

Back

An isotonic solution has an equal concentration of solutes compared to another solution, resulting in no net movement of water into or out of cells.
