Cell Organelles with Their Own Genetic Material
- Some cell organelles contain their own DNA and can replicate independently of the cell's nuclear DNA.
- The primary organelles that have their own genetic material are mitochondria and plastids.
EXPLANATION:
- Mitochondria:
- Mitochondria are known as the powerhouse of the cell as they generate most of the cell's supply of adenosine triphosphate (ATP).
- They have their own circular DNA, which is similar to bacterial DNA, and can replicate independently of the cell's nuclear DNA.
- Plastids:
- Plastids are a group of plant cell organelles that include chloroplasts, chromoplasts, and leucoplasts.
- Chloroplasts, which are involved in photosynthesis, contain their own DNA, which is also circular and similar to bacterial DNA.
- Like mitochondria, plastids can replicate independently of the cell's nuclear DNA.
Therefore, the two cell organelles that have their own genetic material are mitochondria and plastids.
