Three of the following statements regarding cell organelles are correct while one is wrong. Which one is wrong?
Updated On: Jul 27, 2022
- Lysosomes are double membraned vesicles budded off from Golgi apparatus and contain digestive enzymes
- Endoplasmic reticulum consists of a network of membranous tubules and helps in transport, synthesis and secretion
- Leucoplasts are bound by two membranes, lack pigment but contain their own DNA and protein synthesizing machinery
- Sphaerosomes are single membrane bound and are associated with synthesis and storage of lipids
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Double membranes are absent in lysosomes. They are enclosed by single lipoproteinaceous unit membrane. Lysosome is called 'suicidal bag' of the cell due to presence of hydrolytic enzymes.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
