We perform our measurements for KHP at 281 nm. Would we get the same results for pathlength at 250 nm? What about using chlorophyll at 667 nm?
Why might a too high concentration of KHP give erroneous data for measuring pathlength?
If a C3 plant and a C4 plant are placed in separate sealedcontainers and provided with adequate light and water, bothwill survive. If both plants are placed in a single sealed container, the C3 plant will die. Explain.
Two groups of tomatoes were grown under laboratoryconditions, one with humus added to the soil and one acontrol without humus. The leaves of the plants grownwithout humus were yellowish (less green) compared withthose of the plants grown in humus-enriched soil. The bestexplanation is that(A) the healthy plants used the food in the decomposing leavesof the humus for energy to make chlorophyll.(B) the humus made the soil more loosely packed, so waterpenetrated more easily to the roots.(C) the humus contained minerals such as magnesium andiron needed for the synthesis of chlorophyll.(D) the heat released by the decomposing leaves of the humuscaused more rapid growth and chlorophyll synthesis.

- In a population of cyanobacteria (Chlorogloeopsis fritschii) in a hot spring in Iceland, some of the bacteria can produce chlorophyll f, while some C. fritschii produce only other types of chlorophylls. Chlorophyll f absorbs light outside of the visible light spectrum, namely near infrared light, allowing the bacteria to absorb light that has not been absorbed or reflected by the water or other organisms. The ability to produce chlorophyll f is heritable, and the bacteria with chlorophyll f can live in low-light environments, such as underneath other organisms, or near the bottom of the light-penetrating zone of the spring. What is the adaptation in this population of C. fritschii living in low-light environments?
