The Correct Option is A

Solution and Explanation

Both mitochondria and chloroplast are semi-autonomous organelles as they possess their own DNA, RNA and 70S ribosomes to have sufficient functional independence from cellular machinery. Chloroplasts DNA is bigger than mitochondrial DNA. However, genetic information contained in these DNAs is limited. DNA is naked (without histone proteins) in both.

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.
