Question

The organelles that are included in the endomembrane system are :

• A. Endoplasmic reticulum, Mitochondria, Ribosomes and Lysosomes
• B. Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles
• C. Golgicomplex, Mitochondria, Ribosomes and Lysosomes
• D. Golgi complex, Endoplasmic reticulum, Mitochondria and Lysosomes

Answer 1

The Correct Option is B

In this question, we need to identify which organelles are included in the endomembrane system. The endomembrane system is a group of interconnected structures within eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the following organelles:

• Endoplasmic Reticulum (ER): It is divided into rough and smooth regions and is involved in protein and lipid synthesis.
• Golgi Complex: It modifies, sorts, and packages proteins and lipids for secretion or for use within the cell.
• Lysosomes: They contain digestive enzymes and are involved in breaking down macromolecules, old cell parts, and microorganisms.
• Vacuoles: These are large vesicles that can store nutrients, waste products, or help maintain cellular turgidity (in plant cells).

The correct answer encompasses these organelles of the endomembrane system. Based on this information, the correct answer is Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles. This option includes all the necessary components of the endomembrane system.

To evaluate the other options:

• Endoplasmic reticulum, Mitochondria, Ribosomes and Lysosomes: Mitochondria and ribosomes are not part of the endomembrane system. Mitochondria are involved in energy production, and ribosomes are involved in protein synthesis but are not membrane-bound structures associated with the endomembrane system.
• Golgicomplex, Mitochondria, Ribosomes and Lysosomes: Similar to the previous option, mitochondria and ribosomes are not part of the endomembrane system.
• Golgi complex, Endoplasmic reticulum, Mitochondria and Lysosomes: Again, mitochondria are incorrectly included within the endomembrane system.

Therefore, the correct answer is Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles.
