Mitochondria and chloroplasts are known as "semi-autonomous cell organelle".
Reason - They can self duplicate as they have circular DNA, 70S ribosomes, mRNA, tRNA, rRNA (for protein synthesis), required for duplication.
Mitochondria and chloroplasts are also known as "bacterial endosymbionts".
Reasons -
1. ETS (mechanism from which ATP sythesis occurs) is present
2. Presence of own nucleic acids and 70S ribosomes
3. Membranes resemble with that of bacteria (presence of proteins called porins)
