The correct answer is 1 and 3 only.

Key Points

Lysosomes:

• It is called the “suicidal bags” of the cell. Hence statement 1 is correct.
• It is also known as the is called the perinuclear dense bodies.
• The lysosomal membrane is rich in Sialic acid. Hence statement 2 is not correct.
• They are absent in Erythrocytes. Hence statement 3 is correct.
• They are acidic in nature due to the presence of anabolic enzymes. Hence statement 4 is not correct.
• Acid phosphatase (Enzyme) is used as a marker for the lysosomes.
• Sucrose density gradient centrifugation is used in the isolation of Liposomal fractions.
• Functions of lysosomes:
  • Autolysis
  • Autophagy
  • Digestion (intracellular and extracellular)
• Gamori staining techniques are used to locate the lysosomes.
• Phosphate esters and nucleases are the components of lysosomes.
• They are considered the “garbage trucks” of a cell because they remove all unwanted cellular materials.
• White blood cells contain the most active lysosomes.
• They are involved in Secretion.
• They are found in Leukocytes.
