Use the data to create a graph in Excel. It should be a scatter plot with a line connecting each point. Looking at the graph: a/ Which wavelengths absorbed most by spinach and likely used for photosynthesis? b/ Which wavelengths are absorbed least?

Which of the following are the inputs of the light reactions? Choose all that apply. carbon dioxide gas O NADP+ ADP+P oxygen gas АТР water O NADPH sunlight

Chlorophyll is the dominant pigment in photosynthetic cells, and degrades earlier than carotenoids in the fall. Select one: True False

I need a clear and concise definition of photosynthesis.

Construct a bar graph in excel with your mung bean results. Please include appropriate labels and titles. See attached data and inculde the graph here.

What does the results from the absorption spectrum tell you about the specific pigments in the leaf?

DCPIP (2,6-dichlorophenol-indophenol), a blue dye, can act as an electron acceptor and becomes colorless when reduced. A suspension of chloroplasts is prepared, and DCPIP is added to the suspension. The sample is split into two test tubes. One test tube is exposed to light and the other is wrapped in foil (dark control). What would you observe over time comparing the light exposed and the dark control test tubes?   A. The sample exposed to light stays blue. The sample kept in the dark turns colorless.   B. The sample exposed to light turns colorless. The sample wrapped in foil stays blue.   C. Both samples stay blue.   D. Both samples turn colorless.

In hot, dry climates, plants have evolved mechanisms to avoid photorespiration. Which of the following is FALSE Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d C3 plants have no mechanism to avoid photorespiration C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light- independent reaction in the bundle-sheath cells CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata closed during the day C4 plants include corn, sugarcane, and many grasses CAM plants can undergo photophosphorylation in the absence of sunlight 7 Open in Readin

The lab instructor will have a photosynthesis demonstration set up for your observation. What product are we observing?
