The Correct Option is A

Solution and Explanation

Lysosomes were discovered by Christian de Duve $(1955)$ from rat liver. Matile $(1964)$ discovered lysosomes in plants. Generally lysosomes are $0.2 - 0.8 \,\mu$ in size, irregular membranous vesicles filled with hydrolytic enzymes. They are polymorphic. About $40$ enzymes (all hydrolytic) are present in lysosomes. These include proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases and sulfatases.

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.
