Students are studying the rate of photosynthesis in bean plants. Which of the following environmental condition changes would MOST directly affect the photosynthetic activity of the plant cells?
increased levels of simple sugars within the plant
Students conducting an experiment on rates of photosynthesis place just–watered plants in an airtight glass case like the one shown in the diagram above. The plants are not given any more air or water and receive only the sunlight during the experiment. At the end of the experiment students notice __________
