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.
