Concept explainers
WRITE ABOUT A THEME: ENERGY AND MATTER Life is solar powered. Almost all the producers of the biosphere depend on energy from the sun to produce the organic molecules that supply the energy and carbon skeletons needed for life. In a short essay (100–150 words), describe how the process of photosynthesis in the chloroplasts of plants transforms the energy of sunlight into the chemical energy of sugar molecules.

- Photosynthesis is the basis for food production on Planet Earth. To fill in the blanks below, choose among the following terms: Word Bank: Glucose, H₂O, O2, CO2, sunlight In Photosynthesis, 6 molecules of + 6 molecules of + + 6 molecules of produce 1 molecule ofarrow_forwardReview the overall equation of photosynthesis. I nen, use the terms and phrases to complete the concept map. Each answer dock may require one or several labels. Some labels will not be used. Life consists of units called Cells consist of Molecules consist of Atoms Amino acids Triglycerides carry out the functions of is the scientific study of H₂O include DNA N₁ ATP Carbohydrates Proteins encodes such as Enzymes UV light Co, Biology makes uses makes Cellular respiration Light Photosynthesis catalyze the cell's chemical reactions, including byproducts Include requiresarrow_forwardThe process of photosynthesis can be modeled in various ways. For example, a chemical equation is one way to represent photosynthesis. 6CO, + 6H,0 ++ +→ 60, + C,H,,O,arrow_forward
- 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?arrow_forwardLight is a form of electromagnetic energy. The electromagnetic spectrum is made of various forms of electromagnetic energy, such as x-rays, UV, and microwaves. Visible light is used in photosynthesis. What is visible light? How are energy and wavelength related to each other? The overall goal of photosynthesis is to make harness the energy of the sun and store it in the chemical bonds of “food.” In your own words describe the goals of the two sets of reactions of photosynthesis: a.The goal of the light reactions b. The goal of the Calvin cyclearrow_forwardA botanist has been examining three plants, measuring the amount of acid in their cells and examining sections of their leaves under the microscope.

- Adjusting the wavelength of light and increasing the temperature can increase the rate of photosynthesis. Using specifics, describe in detail the effect of wavelength and temperature on photosynthesis and why or how these 2 factors affect the creation of the molecules used in or produced by photosynthesis.arrow_forwardDraw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration. Ribulose, CO2, rubisco, phosphoglycerate (PGA), bisphosphoglycerate, phosphoglyceraldehyde (PGAL), ATP, ADP, NADPH, NADP, kinase, fructose, and glucose should appear.arrow_forwardThree plants grow side by side in a pond. Glucose and starch are measured for each and shown in relative units below, along with the pH of the vacuole at dawn and at noon.

Where does the chloroplast or Cyanobacterium obtain these electrons? From carbon dioxide From sunlight From water From ATParrow_forwardDiagram 3: Light Wave Absorption of Chlorophyll a and b. Chlorophyll a Chlorophyll b 400 450 500 550 600 650 700 Wavelength (nm) Plant chlorophyll chemicals will absorb, or take in, light wave energy in order to produce their own organic molecules used for cellular energy. Reflected light refers to those wavelengths of light that will "bounce off" of the chlorophyll and not be absorbed. Select the conclusion that most accurately summarizes the data in diagram 3. Red and blue light waves have equal importance during photosynthesis. The majority of light energy is attained from red light, while the blue light waves provide additional light energy to photosynthesis. The majority of light energy is attained from blue light, while the red light waves provide additional light energy to photosynthesis. Medium length light waves are important to photosynthesis Absorptionarrow_forward
