<h2>Cell Analogy</h2>

Explanation:

  • Nucleus: Parents

As we see that parents control everything in the house. Similarly,the nucleus controls everything in the cell.

  • Cell membrane: Door

A door is analogous to the cell membrane because it allows people come and go. Similarly,the cell membrane in a cell can allow certain things to enter and exit.

  • Cytoplasm: Air

The cytoplasm fills the space in a cell. It is similar to air which is filled everywhere in the house.

  • Nuclear membrane: Security guard

The nucleus in a cell is protected by nuclear membrane. The nuclear membrane is analogous to secuity guard. As people in a house are protected by security guard, similarly nucleus is protected by nuclear membrane.

  • Endoplasmic reticulum: Hall ways

Endoplasmic reticulum transport things to other places in the cell. It is similar to hallways which help us to reach different places in the house.

  • Golgi bodies: Car

The golgi bodies modify,sort and package proteins.

It send them to other parts of the cell when needed.

It is similar to a Car which transports people and can store stuffs.

  • Mitochondria: Stove

The mitochondria in a house is analogous to Stove as it breaks down nutrients and turns them into energy. Similarly, the Stove in our house, cooks foods and it is converted into energy when consumed.

De acuerdo con lo anterior llene el siguiente cuadro comparativo señalando con x si las células procariotas o eucariotas posee l
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.
