QUESTION 1
¿Por qué la membrana plasmática es crucial para la célula?
Separa la célula del medio ambiente y de otras células
Contiene el ADN de la célula
Permite que la célula produzca energía para funciones básic
Permite que la célula metabolice para formar proteínas



Answer :

The plasma membrane is crucial for the cell because: 1. It separates the cell from the external environment and from other cells. This separation is essential for maintaining the cell's internal environment, controlling what enters and leaves the cell, and protecting it from harmful substances. 2. It does not contain the cell's DNA. The DNA of the cell is typically found within the nucleus, a separate structure within the cell. 3. The plasma membrane allows the cell to produce energy for basic functions. This is achieved through processes like cellular respiration and photosynthesis, which occur across the membrane. 4. It enables the cell to metabolize and form proteins. The plasma membrane plays a role in transporting molecules in and out of the cell, which is essential for cellular metabolism and protein synthesis. In summary, the plasma membrane is a vital component of the cell that helps maintain its integrity, regulate its internal environment, produce energy, and carry out essential metabolic processes.
