The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory.

Some of the evidences in support of this theory are mentioned below:
- Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.

- The associated ribosomes are similar to the bacterial ribosomes.
- Presence of porins in these organelles similar the bacterial membrane.
“Lord Randall” is a Scottish ballad in the form of a narrative song. A narrative song is a song that depicts or tells a story. A ballad is unique for it directly tells a story and emphasizes climactic incidents. It strips away those details which are not important to the plot. The story of “Lord Randall” narrates about a man who has been poisoned by his lover. The story does not tell about the incident’s background nor is the audience aware why the man has been poisoned. The story just shows the man revealing that he has been poisoned, his statement of his last will and testament, and his curse on the lover who planned to kill him.
