Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Lysosomes are believed to be formed by the joint activity of endoplasmic reticulum, endosomes and Golgi complex (GERL system). The precursors of hydrolytic enzymes are mostly synthesised at the rough endoplasmic reticulum. The latter transfers them to the forming face of Golgi complex either directly or from smooth endoplasmic reticulum through its vesicles. In Golgi complex, the precursors are changed to enzymes. The enzymes are then packed in larger vesicles which are pinched off from the maturing face. Golgian vesicles are joined by endosomes to produce lysosomes.

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.
