Answer:

The phospholipid bilayer builds the principle structural frame of the plasma membrane of the cell.

Explanation:

The plasma membrane of both plant and animal cell contain phospholipid bilayer in which the head group of the Phospholipid are oriented in opposite direction with respect to each other whereas the fatty acid tails of the two  layers faces each other each other in the phospholipid bilayer.

        The polar head group is present in the hydrophilic region whereas the non polar fatty acid tails are present in the hydrophobic region.

               Beside phospholipid  glycolipid,cholesterol and proteins are also present in the phospholipid bilayer.

                   Glycolipid contain oligosaccharide chain which play an important role in recognisation and binding of various molecules. Membrane proteins helps in the transport of various molecules in and out of the cell.whereas cholesterol regulates membrane fluidity.

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.
