Different cell organelles such as the Golgi apparatus, endoplasmic reticulum, and lysosomes, together constitute the basic structural and functional unit of life called the:
Tissue
Organ
Cell
Organism
Cell
The cell is defined as the fundamental structural and functional unit of life because it contains specialized membrane-bound organelles that perform all life processes. Organelles like the Golgi apparatus, endoplasmic reticulum, and lysosomes work in a coordinated system, often referred to as the endomembrane system, to sustain cellular metabolism.

Organelles like the Golgi apparatus, endoplasmic reticulum, and lysosomes work in a coordinated system, often referred to as the endomembrane system, to sustain cellular metabolism.
Think of a cell as a fully functional city: the Endoplasmic Reticulum is the manufacturing factory, the Golgi apparatus is the post office/shipping center, and lysosomes are the waste management and recycling plants.
G-E-L: Golgi, Endoplasmic Reticulum, Lysosomes (Components of the endomembrane system)
pH=тИТlog10тАЛ[H+] тАФ calculation of acidic environment within lysosomes
Cellular function is achieved through compartmentalization. The Endoplasmic Reticulum synthesizes proteins and lipids, the Golgi apparatus modifies and packages these products into vesicles, and lysosomes contain hydrolytic enzymes (active at acidic pHтЙИ5.0) to digest waste, effectively managing the cell's internal economy.
The cell is the basic building block of all living organisms (Cell Theory).
Organelles are subcellular structures that perform specific metabolic functions.
The Golgi apparatus and ER are central to the protein secretory pathway.
Lysosomes act as the 'suicide bags' or digestive centers of the cell.
Compartmentalization allows incompatible chemical reactions to occur simultaneously within a single cell.
Protein synthesis in industrial biotechnology
Study of genetic disorders caused by organelle malfunction (e.g., lysosomal storage diseases)
The term 'cell' was first coined by Robert Hooke in 1665.
Option A (Tissue) is a group of similar cells performing a specific function.
Option B (Organ) is a structure composed of different tissues.
Option D (Organism) is the complete living entity resulting from complex organ system integration.
C is correct тАФ The Golgi apparatus, endoplasmic reticulum, and lysosomes are specialized organelles within a cell that cooperate to perform vital life functions.
Always remember the hierarchy: Cells тЖТ Tissues тЖТ Organs тЖТ Organ Systems тЖТ Organism. Questions often switch these levels to confuse candidates.
