To determine which of the cell organelles listed are semi-autonomous, let’s analyze the options provided:

1. Endoplasmic Reticulum (ER): This organelle is responsible for the synthesis of proteins and lipids but does not have its own genome or the ability to replicate independently. Therefore, it is not considered semi-autonomous.

2. Lysosomes: These are involved in the breakdown of macromolecules and are not capable of independent replication or contain their own DNA. Thus, they are not semi-autonomous.

3. Plastids: Particularly found in plant cells, plastids like chloroplasts have their own DNA and can replicate independently of the cell division process. Therefore, they are considered semi-autonomous.

4. Mitochondria: These organelles are known as the powerhouses of the cell, generating ATP through cellular respiration. Mitochondria also contain their own DNA and replicate independently, making them semi-autonomous as well.

In summary, the semi-autonomous cell organelles from the provided options are C: Plastids and D: Mitochondria.

Final Answer

The semi-autonomous cell organelles are C: Plastids and D: Mitochondria.
