Answer: The plasma membrane is the outer barrier of the cell that separates the inside from the outside environment, while organelles are specialized structures within the cell that perform specific functions necessary for the cell's survival and function.
Explanation: The plasma membrane, also known as the cell membrane, is a thin, flexible barrier that surrounds the cell and separates the inside from the outside environment. It is composed of lipids and proteins and plays a crucial role in maintaining the integrity and function of the cell.
On the other hand, organelles are specialized structures within the cell that perform specific functions. Some examples of organelles include the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.
The nucleus is the central organelle that controls the cell's genetic material and is involved in the synthesis of proteins. The mitochondria are the cell's powerhouses, responsible for producing energy in the form of ATP. The endoplasmic reticulum is involved in the synthesis and transportation of proteins, while the Golgi apparatus is responsible for modifying, sorting, and transporting proteins and lipids.
