Question

Cell organelle responsible for autolysis:

• A. Dictyosome
• B. Lysosome
• C. Peroxisome
• D. Glyoxysome

Answer 1

The correct option is B

Lysosome

The correct option is B:

Explanation of the correct option:

1. Lysosomes are tiny spherical sac-like structures that are suspended in the cytoplasm.
2. They are bounded by a single membrane.
3. They are rich in hydrolytic enzymes.
4. In autolysis or autodigestion, the lysosomes of a cell burst to break down the cell completely.
5. Old cells are removed by autolysis.
6. Lysosomes are also called suicidal bags of cells.

Explanation of the incorrect option:

Option A:

1. In the plant cells, Golgi bodies are called dictyosomes as it is made up of unconnected units.
2. Dictyosomes help in modifying proteins from the endoplasmic reticulum.

Option C:

1. Peroxisomes are membrane-bound minute vesicles that contain various enzymes.
2. Helps in the oxidation of long-chain fatty acids.

Option D:

1. Glyoxysomes are specialised peroxisomes and occur only in plants.
2. Helps in the conversion of fatty acids to carbohydrates.

Final answer: The Cell organelle responsible for autolysis is the lysosome.
