CHE SIGNIFICA PHOTOTROPIC IN INGLESE
phototropism
Il fototropismo è la crescita degli organismi in risposta alla luce. È osservato più spesso nelle piante, ma può anche avvenire in altri organismi come i funghi. La crescita o il movimento di una parte vegetale in risposta a una fonte di luce. Le cellule della pianta più lontane dalla luce hanno una sostanza chimica chiamata auxina che reagisce quando si verifica fototropismo. Ciò provoca che l'impianto abbia delle cellule allungate sul lato più lontano dalla luce. Il fototropismo è uno dei molti tropismi vegetali o movimenti che rispondono agli stimoli esterni. La crescita verso una sorgente luminosa è chiamata fototropismo positivo, mentre la crescita lontana dalla luce è chiamata phototropism negativo. La maggior parte dei germogli delle piante esprimono fototropismo positivo e riorganizzano i loro cloroplasti nelle foglie per massimizzare l'energia fotosintetica e promuovere la crescita. Le radici di solito mostrano fototropismo negativo, anche se il gravitropismo può svolgere un ruolo più importante nel comportamento e nella crescita delle radici. Alcuni spuntini di vite producono fototropismo negativo, che permette loro di crescere verso oggetti scuri e solidi e salire su di loro. La combinazione di fototropismo e gravitropismo permettono alle piante di crescere nella giusta direzione.
definizione di phototropic nel dizionario inglese
La definizione di fototropico nel dizionario è relativa alla risposta di crescita delle parti della pianta allo stimolo della luce, producendo una flessione verso la sorgente luminosa.

CITAZIONI IN INGLESE CON «PHOTOTROPIC»
Citazioni e frasi famose con la parola
phototropic.
Biological energy comes from the sun. Light energy harvested by photosynthesis in chloroplasts and phototropic bacteria becomes stored in carbohydrates and fats. This stored energy can be released by oxidative metabolism in the form of adenosine triphosphate (ATP) and used as fuel for other biological processes.
