Question

Semiautonomous cell organelle is :&#8211;a)Mitochondriab)Ribosomec)Plasma membraned)PeroxysomeCorrect answer is option 'A'. Can you explain this answer?

Answer

Mitochondria and chloroplast are called as semi autonomous because they have their own DNA which can replicate independently. These organelle posses their own ribosomes. They synthesize some of their own proteins while dependent on nucleus for other proteins.

Answer

Mitochondria have it's own DNA  hence they can replicate themselves though it depends on nucleus for proteins. Hence mitochondria is called as semiautonomous organelle.

Answer

It is a semi autonomous organelle because it has its own DNA and can replicate by its own

Answer

Happy new year guys

Answer

Introduction:
Semiautonomous cell organelles are those organelles which possess their own genetic material (DNA) and can replicate independently to some extent within the cell. They are considered to be semi-independent because they are not completely self-sufficient and still rely on the cell for certain functions. One example of a semiautonomous cell organelle is the mitochondria.

Mitochondria:
- The mitochondria are double-membraned semiautonomous organelles found in most eukaryotic cells.
- They are often referred to as the 'powerhouses' of the cell due to their role in producing energy in the form of ATP through cellular respiration.
- Mitochondria have their own DNA, known as mitochondrial DNA (mtDNA), which is separate from the nuclear DNA found in the cell's nucleus.
- They also have their own ribosomes and can synthesize some of their own proteins.
- Mitochondria can replicate independently by a process called fission, where they divide into two separate organelles.
- They are involved in various cellular processes such as metabolism, calcium storage, apoptosis (programmed cell death), and regulation of cell signaling pathways.

Function:
- One of the main functions of mitochondria is to generate ATP through oxidative phosphorylation, a process that occurs in the inner mitochondrial membrane.
- They play a crucial role in the production of energy required for various cellular activities, including muscle contraction, cell division, and active transport of molecules across the cell membrane.
- Mitochondria are also involved in the metabolism of lipids, amino acids, and carbohydrates.
- They regulate calcium levels within the cell, which is important for signaling processes and maintaining cellular homeostasis.
- Mitochondria are essential for programmed cell death or apoptosis, as they release certain proteins that initiate the process.
- They are also involved in the production of reactive oxygen species (ROS) and have antioxidant defense mechanisms to protect the cell from oxidative damage.

Conclusion:
In conclusion, mitochondria are semiautonomous cell organelles that possess their own DNA and can replicate independently within the cell. They are involved in various cellular processes, including energy production, metabolism, calcium regulation, apoptosis, and cell signaling.
