¿para que sirven los plasmodesmos?
stiv31 [10]

Answer:

Los plasmodesmos forman una ruta importante para la comunicación entre las células vegetales. Regulan la comunicación de célula a célula, permitiendo así la diferenciación de órganos y tejidos vegetales.

Los plasmodesmos facilitan el movimiento de moléculas entre las células, desde pequeños productos fotosintéticos hasta grandes proteínas y ARNm. En el tejido vascular, los plasmodesmos son cruciales para el movimiento de nutrientes. También son cruciales durante el desarrollo porque, a diferencia de las células animales, las células vegetales no se mueven. Por tanto, la expresión correcta de genes tanto temporal como espacialmente es importante. Mientras que las células vegetales, como las células animales, son capaces de interactuar receptor-ligando para enviar señales a otras células, los plasmodesmos ofrecen contacto directo. Además, el tamaño de la manga difiere en diferentes tipos de células y tejidos vegetales. Por tanto, los plasmodesmos son un componente celular activo en el transporte intercelular, durante el desarrollo y en el tejido maduro.
