O QUE SIGNIFICA PLASMODESMA EM INGLÊS
Plasmodesma
Plasmodesmata são canais microscópicos que atravessam as paredes celulares das células vegetais e algumas células de algas, permitindo o transporte ea comunicação entre elas. Os plasmodesmata evoluíram independentemente em várias linhagens, e as espécies que possuem essas estruturas incluem membros das Charophyceae, Charales, Coleochaetales e Phaeophyceae, bem como todos os embriofitos, mais conhecidos como plantas terrestres. Ao contrário das células animais, cada célula vegetal é cercada por uma parede celular polissacarídica. As células das plantas vizinhas são, portanto, separadas por um par de paredes celulares e a lamela intermediária intermediária, formando um domínio extracelular conhecido como apoplast. Embora as paredes celulares sejam permeáveis a pequenas proteínas solúveis e outros solutos, os plasmodesmata permitem o transporte intercelular direto, regulado e simplásico de substâncias entre células. Existem duas formas de plasmodesmata: plasmodesmata primários, que são formados durante a divisão celular, e plasmodesmata secundários, que podem se formar entre células maduras. Estruturas semelhantes, chamadas junções de lacunas e nanotubos de membrana, interconexão de células animais e estromas formam-se entre plastidios em células vegetais.
definição de plasmodesma no dicionário inglês
A definição de plasmodesma no dicionário é qualquer um dos vários fios citoplasmáticos muito finos que conectam o citoplasma de células adjacentes através de pequenos orifícios nas paredes celulares.
