Information
has glosseng: A solution is hypertonic when there are more solutes outside of a cell than inside. Over time the cell will lose water through the passive process of osmosis (i.e from a high concentration to a low concentration of water molecules). When a cell is placed in a hypertonic solution, the water diffuses (moves) out of the cell, causing the cell to shrivel. An example of a hypertonic solution is saltwater.
has glosseng: Tonicity is a measure of the osmotic pressure (as defined by the water potential of the two solutions) of two solutions separated by a semipermeable membrane. It is commonly used when describing the response of cells immersed in an external solution. Like osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always be in equal concentrations on both sides of the membrane.

Meaning
Czech
has glossces: Tonicita je osmolalita roztoku ve vztahu k buňce. Je rovná koncentraci rozpuštěných látek, které jsou schopné putovat přes polopropustnou membránu. Známe tři druhy tonicity: hypertonicita, hypotonicita a izotonicita.

French
has glossfra: En biologie, un environnement cellulaire hypertonique est un environnement ayant une concentration supérieure en solutés à celle du cytoplasme. Dans un environnement hypertonique, losmose incite leau à quitter la cellule ; le cytoplasme peut ainsi devenir si concentré que la cellule a des difficultés à fonctionner.

Italian
has glossita: La tonicità è una misura comparativa della pressione osmotica di due soluzioni separate da una membrana semipermeabile. È comunemente impiegata per descrivere le reazioni delle cellule quando vengono immerse in una soluzione esterna. Come la pressione osmotica, la tonicità dipende soltanto dai soluti che non possono superare la membrana, poiché solo questi ultimi esercitano una pressione osmotica. I soluti che oltrepassano la membrana, invece, non condizionano la tonicità, perché saranno sempre in uguale concentrazione su entrambi i lati della membrana.

has glosskat: ჰიპერტონიური ხსნარი – ოსმოსის დროს, მეტად კონცენტრირებული ხსნარი. ბიოლოგია–ში ხსნარი, რომელშიც უჯრედის ციტოპლაზმასთან შედარებით მეტი ნივთიერებებია გახსნილი. ასეთ ხსნარში მოთავსებისას, ოსმოსური წნევის გამო, უჯრედი წყალს კარგავს.

Portuguese
has glosspor: Fala-se de solução hipertônica (ou hipertónica) quando a concentração de soluto de uma solução "x" é maior que a concentração "y" de uma outra solução, separada da solução "x" por uma membrana semipermeável .
lexicalizationpor: Meio Hipertónico
Castilian
has glossspa: En biología, una solución hipertónica es aquella que tiene mayor concentración de soluto en el medio externo y la célula pierde agua (H2O) debido a la diferencia de presión osmótica; la célula puede llegar a morir por deshidratación. La salida del agua de la célula continúa hasta que la presión osmótica del medio externo y de la célula sean iguales. Fenómenos similares ocurren al conservar alimentos en salmueras o jarabes concentrados de azúcar.

Vietnamese
has glossvie: Ưu trương (tiếng Anh: hypertonic) là môi trường mà nồng độ chất hoà tan lớn hơn so với môi trường nội bào. Nếu một tế bào sống được đặt trong môi trường ưu trương so với nó thì sẽ xảy ra hiện tượng co nguyên sinh - nước từ trong tế bào sẽ đi ra ngoài làm cho tế bào bị co (thu nhỏ lại) và nếu co quá nhiều sẽ làm tế bào chết.
