The word "hypotonic" is commonly used in biology and medicine to describe a solution with lower concentration of solutes than another solution. Its phonetic transcription in IPA is /ˌhaɪpəˈtɒnɪk/. The first syllable "hy-" is pronounced with a long i sound, followed by the stressed syllable "-po-", which is pronounced with a schwa sound followed by a short o. The final syllable "-tonic" is pronounced with a short o sound and a stressed i. Overall, the word "hypotonic" is spelled as it sounds, making it easier for people to remember its pronunciation.
Hypotonic refers to a condition or state characterized by having a lower concentration of solute particles outside a cell or in a solution compared to the inside of the cell. In other words, it signifies a relatively lower osmotic pressure in the external environment compared to the internal environment of a cell. This difference in solute concentration between the inside and outside of a cell creates an osmotic gradient that can affect cellular functions.
In a hypotonic solution, water molecules tend to move into the cell, causing it to swell or potentially burst in extreme cases. This process is known as osmosis. The lower concentration of solutes in the hypotonic solution leads to less water being required to balance the concentration on both sides of the cell membrane. This phenomenon is commonly observed in biological systems, such as plant and animal cells.
In the context of medical science, hypotonicity can be used in treatments, such as intravenous fluids, to replenish body fluids and maintain electrolyte balance. However, prolonged exposure to a hypotonic environment can have detrimental effects, particularly on red blood cells, as the excess water influx can cause them to burst or undergo hemolysis.
Overall, hypotonic is a term used to describe a solution or condition where there is a lower concentration of solute particles outside a cell, leading to the movement of water molecules into the cell and potentially affecting its structure and function.

The word "hypotonic" has its roots in the Greek language. It is formed by combining two Greek words: "hypo" meaning "under" or "below", and "tonos" meaning "tension" or "tone". Thus, "hypotonic" can be understood to mean "having a lower tension or tone". In the context of biology and medicine, "hypotonic" is often used to refer to a solution with a lower concentration of solutes compared to another solution, resulting in a lower osmotic pressure.
