ЧТО ОЗНАЧАЕТ СЛОВО CHROMATOPHORE
хроматофор
Хроматофоры представляют собой пигмент-содержащие и светоотражающие органеллы в клетках, встречающихся у широкого круга животных, включая амфибий, рыб, рептилий, ракообразных, головоногих моллюсков и бактерий. Млекопитающие и птицы, напротив, имеют класс клеток, называемых меланоцитами с аналогичной функцией. Хроматофоры в значительной степени ответственны за формирование цвета кожи и глаз у хладнокровных животных и генерируются в нервном гребне во время эмбрионального развития. Зрелые хроматофоры сгруппированы в подклассы на основе их цвета под белым светом: ксантофоры, эритрофы, иридофоры, лейкофоры, меланофоры и цианофоры. Термин хроматофор может также относиться к цветным связанным с мембраной везикулам, обнаруженным в некоторых формах фотосинтезирующих бактерий. Везикул Некоторые виды могут быстро изменять цвет через механизмы, которые транслоцируют пигментные и переориентирующие отражающие пластины в хроматофорах. Этот процесс, часто используемый как тип маскировки, называется физиологическим изменением цвета или метахрозом.
Значение слова chromatophore в словаре английский языка
Определение хромофора в словаре - это клетка в коже лягушек, хамелеонов и т. Д., В которых пигмент концентрируется или рассеивается, заставляя животное менять цвет.
