14 Which of the Following Are Shapes of Prokaryotic Cells

Genetic sequencing was used to show that a separate branch of ancient prokaryotic organisms diverged at an early stage in the history of life on Earth Fig. Unlike prokaryotic cells in which DNA is loosely contained in the nucleoid region eukaryotic cells possess a nucleus which is surrounded by a complex nuclear membrane that houses the DNA genome Figure 3.

. Thus a few bacteria are much larger than the average eukaryotic cell typical plant and animal cells are around 10 to 50 µm in diameter. Mycobacterium tuberculosis Flavobacterium capsulatum legionella pneumophila. Thus Woese suggested dividing the prokaryotic organisms into two major categories Bacteria and Archaea based on these genetic differences.

By containing the cells DNA the nucleus ultimately controls all activities of the cell and also serves an essential role in reproduction and heredity. Shape of Bacterial Cell.
