Almost all of the oxygen gas in today’s atmosphere ispresent as a result ofa. outgassing from volcanoes.b. aerobic respiration.c. endosymbiosis.d. photosynthesis.
Define the following terms: a. Calvin cycle b. carbon fixation c. C3 metabolism d. C4 metabolism e. rubisco
a. A researcher set up a greenhouse to study the effects of different parameters
that can influence the rate of photosynthesis. The researcher transplanted 3
plants of different species, a C3 plant, a C4 plant, and a CAM plant.
Meanwhile, the researcher also measures the temperature (°C), humidity (%),
and carbon dioxide content (%) in the greenhouse. The figure below is the
recorded parameters within 24 hours.

Other measured parameters are reported below: -
• Humidity = 20%
• Soil Moisture = Low
Each plant was attached with a probe monitoring amount of glucose or
complex carbohydrate produced during this experiment. Hypothetically, the
carefully selected plants should produce the same amount of glucose in the
same optimum environment (25°C, 65% humidity, 0.04% carbon dioxide,
under sunlight). However, the plants' production of glucose varied in the
record.
