Which one of the following is called the suicidal sacs of the cell?
1 Golgi body
2 Lysosomes
3 Ribosomes
4 Macrosomes
Explanation:
Lysosomes are membrane enclosed organelles that contain array of enzyme capable of breaking down all types of biological polymers. One of its main function is to digest materials taken up from outside the cell. The process is called Endocytosis, that why it is called as Suicidal sac of the cell.

Assertion : ER acts as a circulatory system of cell. Reason : ER functions as cytoskeleton.
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false
Explanation:
Endoplasmic reticulum functions as cytoskeleton or intracellular and ultrastructural skeletal framework by providing mechanical support to colloidal cytoplasmic matrix. The endoplasmic reticulum may act as a circulatory system for intracellular circulation of various substances. Membrane flow may also be an important mechanism for carrying particles, molecules and ions into and out of the cells.

Which of these cell organelles is not considered as endomembrane system
1 ER
2 Golgi complex
3 Mitochondria
4 Lysosomes
Explanation:
Functions of mitochondria are not coordinated with endo-membrane system, hence it is not considered or included under endomembrane system.
