To support the endosymbiotic theory, the following pieces of evidence apply:
- **a. Mitochondria and Chloroplast are the same size**: This supports the idea that they might have originated from similar free-living prokaryotic organisms.
- **b. Double membrane bound**: Both mitochondria and chloroplasts have double membranes, which is consistent with the idea that they were once independent prokaryotic cells that were engulfed.
- **c. Mitochondria and chloroplast have their own RNA**: The presence of their own ribosomal RNA suggests they can produce some of their own proteins, similar to prokaryotes.
- **d. Mitochondria and chloroplast have their own DNA**: They contain circular DNA similar to bacterial DNA, indicating their prokaryotic origins.
The other options do not support the endosymbiotic theory:
- **e. Mitochondria and chloroplast have their own vesicles**: This is not a recognized evidence supporting endosymbiosis.
- **f. Mitochondria and chloroplast have their own Lysosomes**: This statement is not accurate; lysosomes are not associated specifically with mitochondria or chloroplasts.
Therefore, the correct answers are **a, b, c, and d**.
- **a. Mitochondria and Chloroplast are the same size**: This supports the idea that they might have originated from similar free-living prokaryotic organisms.
