Front

What happens to a cell when it is placed in a hypotonic solution?

Back

The cell expands because water enters the cell.

Front

What is the control center of the cell?

Back

Nucleus

Front

What happens to a cell in a hypertonic solution?

Back

The cell shrinks because water leaves the cell.

Front

Golgi Apparatus

Front

What is the function of the Rough Endoplasmic Reticulum?

Back

It is involved in the synthesis and transport of proteins.

Front

Define osmosis.

Back

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution.

Front

What is the difference between isotonic, hypertonic, and hypotonic solutions?

Back

Isotonic: equal solute concentration; Hypertonic: higher solute concentration outside the cell; Hypotonic: lower solute concentration outside the cell.

Front

What role do mitochondria play in the cell?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.
