He could perform some DNA tests that could show how those species were related. Genome sequencing could show all the differences in DNA nucleotides. The number of changes could then be multiplied by the rate of mutations and the result would show how species were related.
The amoeba is eukaryotic cell while bacteria is prokaryotic
protists have a membrane-bounded nucleus, which bacterial cells lack.
this is because the protists actually have a nucleus, which is an area in the center of the cell with a membrane, and it is full of DNA. In the domains of eubacterian and archaebacteria, these do not have nuclei.

Answer:
The cells present in the stem are part of the xylem and phloem conductive tissues. They are characterized by being elongated and in tubular form because they transport the substances, the xylem transports water and inorganic mineral sales that the root absorbs from the soil. The phloem is responsible for transporting substances synthesized in photosynthesis.
Its tubular and elongated shape facilitates the transport of these substances
