Detailed explanation-1: -Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm). Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA.
Detailed explanation-2: -Answer and Explanation: The correct answer is (c) Mitochondria are not membrane bound. Mitochondria are membrane-boud organelles found in eukaryotic cells.
Detailed explanation-3: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Detailed explanation-4: -Answer and Explanation: The following statement is true about the mitochondrion of a cell: d) It is where cellular respiration occurs. The mitochondria is often called the “powerhouse” of the cell, because the process of cellular respiration releases energy that can be used for other cellular processes.
