Microbiology Test Banks Chapter 5

Protists include- algae and protozoa The eukaryotic cell organelle that most resembles a bacterial cell is the- mitochondria Eukaryotic flagella differ from prokaryotic flagella because only eukaryotic flagella- contain microtubules Cilia are found in certain- Protozoa Chitin is a chemical component of the cell walls of- fungi Cell walls are not found on typical cells of- protozoa The site for ribosomal RNA synthesis in eukaryotes is the- nucleolus When a eukaryotic cell is not undergoing mitosis, the DNA and its associated proteins appear as a visible thread-like mass called the- Chromatin Histones are- proteins associated with DNA in the nucleus The eukaryotic cell's glycocalyx is- mostly polysaccharide Which of the following is found in eukaryotic cells but not in prokaryotic cells? - All of the choices are correct. (Nucleus, mitochondria, endoplasmic reticulum, lysosomes) The endosymbiotic theory says that precursor eukaryotic cells acquired flagella by endosymbiosis with a _____ ancestor, and others gained photosynthetic ability from endosymbiosis with a ____ ancestor. - Spirochete, cyanobacteria The cell's series of tunnel-like membranes functioning in transport and storage are the- endoplasmic reticulum An organelle that is a stack of flattened, membranous sacs and functions to receive, modify, and package proteins for cell secretion is the- Golgi apparatus Which organelle contains cristae where enzymes and electron carries for aerobic respiration are found? - Mitochondria
