The organelles that are included in the endomembrane system are :
- Endoplasmic reticulum, Mitochondria, Ribosomes and Lysosomes
- Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles
- Golgicomplex, Mitochondria, Ribosomes and Lysosomes
- Golgi complex, Endoplasmic reticulum, Mitochondria and Lysosomes
The Correct Option is B
Solution and Explanation
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.

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Eurkaryotic Cells - Golgi Apparatus
The Golgi apparatus is also known as the Golgi complex or the Golgi body. The term is derived from Camillo Golgi, the scientist who discovered the organelle. It can be found in all eukaryotic cells, including plants and animals. They are membrane-bound organelles found in the cell's cytoplasm.
Formation of acrosome: The acrosome is a component of the tip of animal sperms that aids in the digestion of the egg or ovum covering sheath during fertilisation. The Golgi complex produces it with the help of its vesicles.
