Why do we believe chloroplast and mitochondria to be semi-autonomous organelle?
Why do we believe chloroplast and mitochondria to be semi-autonomous organelle?

Solution:

Because chloroplasts have their own DNA, they are referred to as semi-autonomous organelles. Furthermore, they have the ability to create their own energy and do not require the cell. However, the cell controls its replication. The only organelles with their own DNA are chloroplasts and mitochondria.
