Maurinko [17]

Answer:

El cuadro no está presente pero las diferencias principales entre células eucariotas y procariotas son:

Eucariotas:

Tienen núcleo

Tienen organelas

Tienen Vacuolas

Tienen Citoesqueleto

Tienen Cloroplastos

El ADN está asociado a proteínas

El ADN es lineal

Presentan mitocondrias

Presentan un sistema de endomembranas

Procariotas:

No tienen núcleo

No tienen vacuolas

No tienen cloroplastos

No tienen organelas

El ADN no está asociado a proteínas

El ADN es circular

Presenta mesosomas

Explanation:

Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.

In ____________ , signals pass through a cell junction from one cell to adjacent cells. membrane-bound signals bind to receptors
harina [27]
In cell-cell contact , signals pass through a cell junction from one cell to adjacent cells.
Membrane-bound signals bind to receptors on adjacent cells in the process of paracrine signalling.
An example of autocrine signalling is when cells release signals that affect themselves and nearby target cells.
 In synaptic signalling cells release signals that affect nearby target cells. Cells release signals that travel long distances to affect target cells during endocrine signalling.
