Fimbriae
Are the surface appendages that allow a bacterium to stick to a surface
Proteins
Are synthesized ribosomes
Capsule
The sticky,jelly like protective layer outside the cell wall
Plasma membrane
Is a selective barrier, allowing passage of oxygen, nutrients, and wastes
Cell wall
The rigid structure found outside the plasma membrane that surrounds and supports the bacterial cell
Which of the following clues would tell you if a cell is prokaryotic or eukaryotic
Weather or not the cell is partitioned by internal membranes prokaryotic cells lack any internal membranous compartmentalizations
Which of the following correctly matches an organelle with its function
Nucleus- cellular respiration (plant cells have a central vacuole, whereas most animals cells have several smaller vacuoles located throughout the cytoplasm
Prokaryotic cells have
Ribosomes
A cell wall
A plasma membrane
DNA
Which of the following statements concerning cells of bacteria and archaea is correct
DNA is present in both archaea and bacteria
Prokaryotes are classified as belonging to two different domains which are
Bacteria and archaea
ECM proteins are made by ribosomes in which part of a eukaryotic cell
Rough ER
What types of proteins are NOT synthesized in the rough ER
Mitochondrial proteins
Which statement correctly, describes the nuclear envelope of a eukaryotic cells
The nuclear envelope is continuous with the endoplasmic reticulum
Which organelles plays a role in intercellular digestion
Lysosome
A cell has formed a food vacuole as it ingested a food particle, which of the following events is associated with the break down of that food particle
Digestion of food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm. Digestion occurs within vesicle if the digestive enzymes were in the cytosol, they might degrade essential components of the cell
Hydrolytic enzymes must be segregated and packaged to prevent general destruction of cellular components, which of the following organelles contains these hydrolytic enzymes in animal cells
Lysosomes
The liver is involved in detoxification of many poisons and drugs,which of the following structures is primarily involved in the process and therefore abundant in the liver cells
Smooth ER
Which of the following produces and modifies polysaccharides that will be secreted
Golgi apparatus
Mitochondria are found in plants and animal cells
All eukaryotic cells including plant and animal cells, contain mitochondria
Which of the following are common traits of chloroplasts and mitochondria
Both have their own DNA ( Mitochondria and chloroplasts contain their own DNA and ribosomes)
The evolution of eukaryotic cells most likely involved
Endosymbiosis of an aerobic bacterium in a large host cell the endosymbiont evolved into mitochondria
Which animal cell organelles contains enzymes that transfers hydrogen from various substrates to oxygen
Peroxisome
The chemical reactions involved in respiration are identical between prokaryotic and eukaryotic cells. In eukaryotic cells, ATP is synthesized primarily on the inner membrane of the mitochondria, in light of the endosymbiont theory for the evolutionary origin of mitochondria where is most ATP synthesized likely to occur in prokaryotic cells
On the plasma membrane
The cilia and flagella of eukaryotic cells are composed of
Microtubules (Eukaryotic cilia and flagella are composed of microtubles
Movement of vesicles within the cell depends on what cellular structures
Microtubules and motor proteins
The extra cellular matrix is thought to participate in the regulation of animal cell behavior by communicating information from the outside to the inside of the cell via which of the following
Integrins
According to the endosymbiosic theory of the origin of eukaryotic cells, how did mitochondria originate
From engulfed, originally free-living protecobacteria
Which of the following was derived from an ancestral Cyanobacterium
Chloroplast
An individual mixotroph loses its plastids yet continues to survive, which of the following most likely accounts for its continue survival
It engulfs organic material by phagocytosis or by absorption
