1. Choose the microorganism group which do not have a true nuclear membrane and reproduce by binary fission. A) Bacteria B) Fungi C) Nematodes D) Protozoa E) Cestodes 2. The site of energy production in the eukaryotic cell is: A) Ribosome B) Chromosome C) Histones D) Mitochondria E) Nucleus

1. The correct answer is A) Bacteria. Bacteria are a group of microorganisms that do not have a true nuclear membrane and reproduce by binary fission. Binary fission is a type of asexual reproduction where a single cell divides into two identical daughter cells.<br /><br />2. The correct answer is D) Mitochondria. The mitochondria are the site of energy production in eukaryotic cells. They are responsible for generating ATP (adenosine triphosphate), which is the primary energy currency of the cell. The mitochondria are often referred to as the "powerhouse" of the cell because of their role in energy production.
