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.

coldgirl [10]

Answer:

Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.

Explanation:

Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.

Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.
