Biology 1 Exam Pro Questions Review With Solutions

{Ans: }The diagram shows the same plant cell: • after 1 hour in distilled water • after 1 hour in strong sugar solution. (a) Describe two ways in which the cell in the strong sugar solution is different from the cell in distilled water. Explain how the differences between the cell in the strong sugar solution and the cell in distilled water were caused. {Ans: 1)The cell in the sugar solution has a smaller vacuole 2) In the sugar solution the cell membrane is not fully against cell wall b) for the sugar solution plant cell, water moves out of the cell due to osmosis, causing the plant cell to shrink, wheres the plant cell in distilled water, there is a higher concentration of water outside.}The barley roots were able to take up more sulfate ions with oxygen than without oxygen. Explain how. {Ans: uptake was by active transport which requires more energy, requires more energy when oxygen is present.}Cell C is found in the salivary glands. Name the enzyme produced by the salivary glands. {Ans: The enzyme is (salivary) amaylase or carbohydrase}The table shows the concentrations of three mineral ions in the roots of
