1. Movement of molecules through the cell membrane: A). Define the difference between passive transport and active transport, B). Include examples of each. C). For each example specify the type of cell, the name of the membrane protein(s), and the substance that is being transported. 2. Energy and cellular functions: The evolution of the Prokaryotic cell type into the Eukaryotic cell type is about an increase in cell size and complexity. The Chloroplast and the mitochondrion represent important contributors to this process. A). Compare the structure of the Chloroplasts and the Mitochondrion in the evolution of Prokaryotes and Eukaryotes B). How does each contribute to the evolution of and success of the Eukaryote cell type.
1. A scientist synthesized a membrane in the laboratory. The synthetic membrane has allthe properties associated with the cell membranes of living cells, can spontaneously formspheres or bubble-like configurations, which replicate on their own, and react with stimuliin the environment. With these findings, the scientist claims he was able to re-createunder laboratory conditions, what Earth’s first living cells possibly look like. State andbriefly explain/support your opinion about his claim. 2.

A cell is moved from its normal environment in a freshwater river and is suddenly placed into the ocean. What would be the effect of this change in environment on the cell? O 1) It would shrivel because it would lose water. O 2) It would shrivel because it is responding to a hypotonic environment. O 3) It would swell because it is experiencing a hypertonic environment. O 4) It would swell because it would gain water. O 5) Nothing would happen to the cell.
