Concept explainers
For each statement, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the themes (see Chapter 1) and review the examples highlighted in blue in this chapter.

Processes like photosynthesis and respiration allow the carbon cycle to regenerate needed substances by recycling earth’s atoms. A diagram of the carbon cycle is shown. Each arrow represents a process in the cycle. Which explanation best describes the process in the cycle. Which explanation best describes the process that occurs at the arrow marked B? A) plants use carbon dioxide from the atmosphere in the process of photosynthesis to produce glucose B) plants release carbon dioxide into the atmosphere in the process of photosynthesis to produce glucose C) plants use carbon dioxide from the atmosphere in the process of cellular respiration to convert glucose to atp energy D) plants release carbon dioxide into the atmosphere in the process of cellular respiration to convert glucose to atp energyarrow_forwardQ) Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants.arrow_forward

NOTE- include the steps of photosynthesis (light-dependent reactions, ETC, Calvin cycle) and the inputs and outputs at each. Then, need to explain how sugar gets transported from the leaf to be used in cell respiration in the root. Then need to diagram cell respiration, including each stage and the inputs and outputs.arrow_forward7. Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a molecule of glucose that is used for energy in the cells of the plant stem.

In your science journal, write a claim that supports the idea that photosynthesis helps sustain life on Earth, and support that claim with at least one piece of evidence. Use the rubric below to assist you with your response. Criteria Scale Makes Claim about Photosynthesis and Supports Claim with Evidence 2 This response includes both a claim about photosynthesis and its importance, and supports the claim with one piece of factual evidence. 1 This response either lacks both a claim and a piece of evidence, or contains a faulty claim or irrelevant/faulty evidence. 0 This response lacks the required components for partial credit.arrow_forward
- Describe the path of a carbon atom through the carbon cycle. Be sure to include the roles of photosynthesis and respiration in each explanation a) Describe your journey starting as a CO2 molecule in the bottom layer dissolved in the water. Describe at least 3 transformations and the organisms involved. b) Describe the journey starting as a molecule of CO2 in the "atmosphere" of the top layer of the bottle. Describe at least three transformations and the organisms involved. c) How could your eco-columnbe used to model the greenhouse effect?arrow_forwardthe question is: Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root.

Some atp is created straightforwardly during the responses that change glucose. Nonetheless, undeniably more ATP is created later in a cycle known as oxidative phosphorylation. Glycerol is changed over into one of the glycolysis moderate items and hence enters the cell breath pathway. Unsaturated fats go through…arrow_forwardCells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? The photosynthetic reaction releases free energy to the surroundings. The photosynthetic reaction’s free energy is in equilibrium. The reactants of photosynthesis have less free energy than the products. The change in free energy (∆G) of the photosynthetic system is less than zero.arrow_forward
- Background: One of the main drivers of climate change is the emissions of carbon dioxide gas into the atmosphere from the burning of fossil fuels. This has altered the global carbon cycle. using the link below to watch https://youtu.be/xk11DVaAjEA PROMPT: 1) What role does photosynthesis paly in the global carbon cycle? 2) What are fossil fuels and how are they altering the global carbon cycle? 3.

This plant thrives in the diverse ecosystem of the Amazon and, surprisingly, can survive with limited sunlight. This unique attribute of the plant could have potential impacts on both the field of ecology and various industries. Your primary research focus is now to investigate the efficiency of photosynthesis in this plant, specifically analyzing the structure of the chloroplasts and the distribution of pigments (chlorophyll and carotenoids) utilizing microscopy techniques. Both traditional fluorescence microscopy (FM) and CSM are capable of identifying the distribution of pigments (chlorophyll and carotenoids). How does the process of stimulating fluorescence and detection vary between these two microscopy techniques? Given these differences, which method would be more likely to yield superior results for your research? Please provide your reasons, taking…arrow_forward
