Mitochondria are described as 'semi-autonomous' organelles primarily because they :
Possess their own circular DNA and 70S ribosomes
Mitochondria are called semi-autonomous organelles because they possess their own circular DNA (similar to bacterial DNA) and 70S ribosomes, allowing them to synthesise some of their own proteins independently of the nucleus.
They are surrounded by a double membrane (not a single one), they do not carry out photosynthesis (that is a chloroplast function), and they are present in almost all eukaryotic cells, not just plant cells.
Therefore, mitochondria are called semi-autonomous organelles because they possess their own circular DNA and 70S ribosomes.
