Question

Why is mitochondria know as semi autonomous organelles

Answer 1

Hey dear....

Mitochondria is the cell organelle which is present in both plants and animal cell.

It helps in the ATP synthesis by the help of oxysomes.

It is called as semi autonomous organell as it contains its own genetic material and DNA by which it can replicate itself.

Hope it helps...

Answer 2

Mitochondria is considered as autonomous cell organelle due to the following counts :
Mitochondria have their own DNA which can replicate independently. The mitochondrial DNA produces its own mRNA, tRNA and rRNA.
The organelles posses their own ribosomes, called mitoribosomes.
Mitochondria synthesize some of their own structural proteins. However, most of the mitochondrial proteins are synthesized under instructions from cell nucleus.
The organelles synthesize some of the enzymes required for their functioning. e.g. succinate dehydrogenase.
They show hypertrophy .i.e. internal growth.However, both their structure and functioning are controlled by the nucleus of the cell and availability of materials from the cytoplasm. Hence, they are termed as the 'semi-autonomous' cell organelles.
