Photosynthesis and Flow of Energy Quiz

Which of the following best summarizes photosynthesis?

• An adaptation of plants that allows them to add nutrients to the soil

• A chemical reaction involving nitrogen and other atmospheric gases

• A process by which plants produce sugar using the energy of sunlight

• An exchange of gases between animals and the air or water of their habitat

Students are observing an aquatic plant. They understand that the bubbles they see rising from the cut stem of the plant are the gases produced during photosynthesis. Which of the following observations provides the best evidence that light is the source of energy for photosynthesis?

• Plants observed in artificial or in natural light were both seen to produce bubbles.

• The frequency of bubbling increases in bright light and slows to a stop in darkness.

• The orientation of the light seems to have no effect on the production of bubbles.

• The bubbles always rise to the surface of the water, moving towards the light.

The concentration of carbon dioxide in parts per million (ppm) was measured for a closed container in several situations. Which of the following data collected would demonstrate the action of photosynthesis?

• When multiple plants were put in the container, carbon dioxide concentration never got above 1,000 ppm.

• When carbon dioxide concentration went from 800 to 1,000 ppm the temperature in the container went up.

• Plants in the container kept in darkness did not lower the concentration of carbon dioxide below 800 ppm.

• When the container included a plant exposed to light, carbon dioxide concentration went from 800 to 600 ppm.

Students are using beads of different colors to represent the molecules in food. The beads can be connected in chains in different arrangements to represent different kinds of molecules. What is the best way for the students to use the beads to represent the processes of photosynthesis and cellular respiration that allow plants and animals to get the energy they need?

• Take apart all chains and separate the beads by color into groups.

• Connect all the beads together into the longest chain that can be made.

• Connect different combinations of beads into chains so that no two are alike.

• Combine the beads in chains, take them apart, and then put them together in new chains.

Cellular respiration is similar in both plants and animals in what way?

• Energy is required and oxygen is released

• Nitrogen is required and energy is released

• Oxygen is required and energy is released

• Oxygen is required and nitrogen is released

What happens to large molecules, such as carbohydrates, during digestion?

• Small molecules combine to form long chains

• Enzymes break down large molecules into smaller molecules

• Light energy is absorbed to create food

• Large molecules are released as oxygen gas

Photosynthesis and respiration connect in which way:

• Photosynthesis stores energy, respiration releases energy

• Photosynthesis and respiration both store energy

• Photosynthesis and respiration both release energy

• Photosynthesis releases energy, respiration stores energy
