- Question 1 of 10
1. Question
5 point(s)Match the following explanations with the correct term.
Sort elements
- A plant takes in carbon dioxide, water, and sunlight and produces sugars and oxygen.
- the "pores" in leaves (and stems) through which CO2 is taken in and O2 is released during photosynthesis
- the water that evaporates out of stomata when they are open.
- the ratio of carbon dioxide intake to water lost through transpiration.
- enzyme RUBISCO gets oxygen instead of carbon dioxide, which slows down making sugars.
- Photosynthesis
- Stomata
- Transpiration
- Water Use Efficiency (WUE)
- Photorespiration

- Question 4 of 10
4. Question
1 point(s)C4 and Cam plants have a different adaptation to what climate
- Question 5 of 10
5. Question
1 point(s)CAM plants keep stomata closed in daytime, thus reducing loss of water. They can do this because they
- Question 6 of 10
6. Question
1 point(s)Organize the type of photosynthesis beside the correct plant.
Sort elements
- Plants undergo normal photosynthesis in normal conditions, stomata are open during the day.
- Photosynthesizes faster than C3 plants under high light intensity and high temperatures because the CO2 is delivered directly to RUBISCO, not allowing it to grab oxygen and undergo photorespiration.
- Stomata open at night and are usually closed during the day. The CO2 is converted to an acid and stored during the night. During the day, the acid is broken down and the CO2 is released to RUBISCO for photosynthesis
