A) plant cell • B) bacterial cell • C) animal cell • D) virus • E) a and b Which of the following has a cell wall?
True or False Ribosomes are found in eukaryotic, but NOT prokaryotic organisms.
True or False Ribosomes are found in eukaryotic, but NOT prokaryotic organisms.
Completion: Chlorophyll, the pigment that captures the sun’s energy, is found in the_______of the chloroplasts.
Completion: Thylakoids Chlorophyll, the pigment that captures the sun’s energy, is found in the_______of the chloroplasts.
Short answer: Why would skeletal muscle cells that a large number of mitochondria in comparison to a skin cell?
Short answer: Skeletal muscle cells have a high demand for energy. Why would skeletal muscle cells that a large number of mitochondria in comparison to a skin cell?
Short answer: How is the nucleoid region of a prokaryotic cell UNLIKE the nucleus of a eukaryotic cell?
Short answer: The nucleoid region of a prokaryotic cell is NOT membrane bound like the nucleus of a eukaryotic cell. How is the nucleoid region of a prokaryotic cell UNLIKE the nucleus of a eukaryotic cell?
Short answer: Why are the lysosomes of the eukaryotic cell sometimes referred to as the “suicide sacs?”
Short answer: When the cell has reached the end of its life cycle, the lysosomes will release its hydrolytic enzymes and ultimately kill the cell. Why are the lysosomes of the eukaryotic cell sometimes referred to as the “suicide sacs?”

Short answer: Describe the endosymbiotic theory proposed by Lynn Margulis.
Short answer: She proposed that the mitochondria and the chloroplast were once independent, living cells that migrated into a larger prokaryotic cell to become organelles within that cell, eventually giving rise to the eukaryotic cell. Describe the endosymbiotic theory proposed by Lynn Margulis.
Short answer: Who discovered that all plants were made of cells?
Short answer: Schleiden Who discovered that all plants were made of cells?
Short answer: This man concluded that all cells come from pre-existing cells:
Short answer: Virchow This man concluded that all cells come from pre-existing cells:
Short answer: What technology was essential for the development of the cell theory?
Short answer: Microscope What technology was essential for the development of the cell theory?
Question: Why do phospholipids tend to organize into a bilayer in an aqueous environment?
Question: The polar tails, made of glycerol and phosphate, are hydrophilic (water-loving) and will face toward the aqueous environment, while the hydrophobic, fatty acid tails will face away from the aqueous environment. Why do phospholipids tend to organize into a bilayer in an aqueous environment?
How could a microscope help you distinguish the shape of the bacteria that causes infections from those that cause “strep” throat?
Name two functions of pili:1. Bacterial conjugation2. Aids in movement
