What is an example of a semi-autonomous organelle found in both animal and plant cells?
Correct answer: D. Mitochondria
- A. Endoplasmic reticulum
- B. Chloroplast
- C. Golgi apparatus
- D. Mitochondria
Explanation
Mitochondria are semi-autonomous organelles found in both animal and plant cells. They are often referred to as the "powerhouses" of the cell because they are responsible for generating most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. Mitochondria have their own circular DNA and ribosomes, allowing them to produce some of their proteins independently. This characteristic of having their own genetic material and the ability to self-replicate makes mitochondria semi-autonomous organelles.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
