¿para que sirven los plasmodesmos?

Biology
1 answer:
stiv31 [10]3 years ago
4 0

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.

Andrew [12]

Answer:

Fur color that closely matches the eucalyptus bark color

Explanation:

In terms of evolving from land dwellers to tree dwellers, the number of offspring does not matter. Although the ability to run faster is a good evolution for escaping predators, it does not help the koalas evolve to be better tree dwellers (how would you run using only the trees?). Communicating with their peers would be convenient for survival, but it does not help koalas become better tree dwellers. What does help koalas survive better by traveling through the trees is camouflaging with the bark of the tree to hide from predators.

Ancient plant ____________________ found in lake bottoms provides scientists with evidence about ancient climates.
AleksAgata [21]
I believe it's "pollen".

When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.

Hope this helps!
