How is chemosynthesis different from photosynthesis?

• Chemosynthesis does not require enzymes.

• Chemosynthesis can occur in environments without sunlight.

• Chemosynthesis does not require reactants from outside the cell.

• Chemosynthesis produces sugars that organisms use as an energy source.

Students in a biology class conduct an experiment to determine the effect of temperature on the rate of photosynthesis in a plant. They place an Elodea plant into a test tube filled with water. Then, the students place the test tube under a light and slowly increase the temperature. They record their results and display them on a graph as shown. Which statement supports the data?

• The rate of Oxygen is the lowest in section M.

• The rate of Oxygen is the greatest in section M.

• The production of water molecules is greatest in section L.

• The number of carbon dioxide molecules in the beaker is greatest in section K.

Students in a biology class conduct an experiment to determine the effect of temperature on the rate of photosynthesis in a plant. They place an Elodea plant into a test tube filled with water. Then, the students place the test tube under a light and slowly increase the temperature. They record their results and display them on a graph as shown. Which statement explains the effect of temperature on the rate of photosynthesis?

• The rate of photosynthesis is unaffected by the temperature of the water.

• The number of chloroplasts in the cell decreases as temperature increases.

Which inference is supported by the data?

• The plant produces more oxygen as light intensity increases.

• The plant takes in more water when the light intensity decreases.

• The plant requires more energy for photosynthesis at lower light intensities.

• The plant needs less carbon dioxide for photosynthesis at higher light intensities.
