Differentiate the plasma membrane and the organelles.
Plasma membrane is the special boundary that helps control what enters and leaves the cell. Organelles are structures that carry out specific cell functions.
The plasma membrane, also known as the cell membrane, is a thin, semi-permeable barrier that encases the entire cell. It is made up of a lipid bilayer, consisting of phospholipids, cholesterol, and proteins, and serves to control the movement of substances in and out of the cell. The plasma membrane is crucial for maintaining the cell’s internal environment and regulating its interactions with the external environment.
On the other hand, organelles are specialized structures within the cell that perform specific functions necessary for the survival of the cell. Examples of organelles include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Unlike the plasma membrane, organelles are enclosed by a membrane bilayer that is specific to each one. Each organelle has a unique role in the cell, ranging from enzyme creation and energy production to protein synthesis and waste removal.
In summary, while the plasma membrane serves as a barrier that surrounds the entire cell, organelles are internal structures that are responsible for specific cellular functions. Both are crucial components of the cell and work together to maintain cellular homeostasis.
