Biology A Unit 5: Lessons 27-30 Questions and Answers 100% Correct Lesson 27: Lesson 27: What is the chloroplast? The chloroplast is an organelle capable of photosynthesis. What are the products of photosynthesis? glucose and oxygen Study the image. Which label identifies the stroma in the chloroplast? C Where can the chlorophyll molecules used in photosynthesis be found? in the thylakoid membrane What is photosynthesis? XXX WRONG XXX a process by which energy from the sun is used to convert glucose and oxygen into carbon dioxide and water Which of these statements describe a pigment? Select all that apply. A pigment is the substance that gives something its color. A pigment is a molecule that reflects only certain colors of light and absorbs the rest. What is the chloroplast's function? It produces sugar molecules. What organisms are photosynthetic? Select all that apply. some bacteria algae What are the reactants in photosynthesis? Select all that apply. carbon dioxide water Which statements about wavelengths are true? Select all that apply. Wavelengths are measured by the distance between two wave peaks. Short wavelengths have more energy than long wavelengths. What is the thylakoid? a flattened, membrane-bound compartment found inside a chloroplast Which statements correctly describe the grana and stroma? Select two that apply. Inside the outer membranes is a gel-like fluid known as the stroma. Stacks of thylakoid membranes are collectively called grana. Study the image. Identify the part of the chloroplast that contains the chlorophyll molecules. D Lesson 28: Lesson 28: Light-dependent reactions convert light energy to chemical energy in which form? ATP, NADPH What is released when water molecules are split during the light-dependent stage of photosynthesis? electrons What is the function of the Calvin cycle? to synthesize sugar molecules Which are outputs of the light-independent reactions? Select all that apply. 0.67 ADP NADP+ What are the inputs and outputs of photosynthesis? inputs: light energy, carbon dioxide, water outputs: glucose, oxygen How does cellular respiration contribute to the cycling of carbon in an ecosystem? XXX WRONG XXX It takes in carbon from sugars; organisms eventually break down and release carbon. Which statements describe events from the light-dependent stage of photosynthesis? Select all that apply. 0.5 Water molecules are split. Carbon dioxide is consumed. ATP and NADPH are produced. What is the name for a series of reactions that converts carbon dioxide to glucose? light-independent reactions Which of these converts light energy into chemical energy? light-dependent reactions What two products from the light-dependent stage of photosynthesis are used in the light-independent stage? ATP and NADPH Light-dependent reactions require which two inputs to work? light energy and water Identify an event that forms part of the Calvin cycle. Carbon dioxide (CO2) is added to RuBP. Which are the outputs of the light-independent reactions? XXX WRONG XXX sugar, ATP, NADPH oxygen, ATP, NADPH Which are inputs of the light-independent reactions? Select all that apply. ATP NADPH What are the inputs and outputs of aerobic respiration? inputs: glucose, oxygen outputs: carbon dioxide, water How does photosynthesis contribute to the cycling of carbon in an ecosystem? It takes in carbon dioxide and uses it to build sugars.
