Question

the following micrographs show the cells of two organisms. the micrograph on the left shows a bacterium (a prokaryote), and the micrograph on the right shows an alga (a eukaryote). micrographs of two organisms: a bacterium (left) and an alga (right). the images are not shown to scale: the cell on the left is actually much smaller than the cell on the right. complete the table to describe the organisms. characteristic bacterium alga has dna as the genetic material true true has a circular chromosome true true has a nucleus in the cell false true image credits

Explanation:

All living organisms have DNA as their genetic material. Bacteria (prokaryotes) have circular chromosomes and lack a nucleus. Some algae (eukaryotes) can have circular - like extra - chromosomal DNA (e.g., in chloroplasts) and they have a nucleus.

Answer:

Characteristic	Bacterium	Alga
has a circular chromosome	true	true
has a nucleus in the cell	false	true
