Describe the similarities and differences of physical characteristics in diverse organisms. Explain why the life cycles of different organisms have varied lengths. Compare life processes e. Apply the appropriate models to show interactions among organisms in an environment. Describe how selective breeding and biotechnology can alter the genetic composition of organisms.
Explain how materials are characterized by having a specific amount of mass in each unit of volume density. Identify atoms as the basic building blocks of matter and that elements are composed of one type of atom.
Analyze how observations of displacement, velocity , and acceleration provide necessary and sufficient evidence for the existence of forces. Describe how energy can be changed from one form to another transformed as it moves through a system or transferred from one system to another system.
Explain and demonstrate how electric current produces magnetic forces and how moving magnets produce electric current. Demonstrate that heat is often produced as energy is transformed through a system. Identify the initial reactants, final products, and general purposes of photosynthesis and cellular respiration.
Describe the relationship between photosynthesis and cellular respiration in photosynthetic organisms. In this lesson, students will learn how living things obtain energy through cell respiration. Students will:. Cell Respiration: The process by which cells use oxygen to break down food molecules and release their stored energy.
ATP Adenosine Triphosphate : A high-energy molecule that cells use for processes such as growth and movement. Mitochondria: The cell organelles where cell respiration takes place. Mitochondrion refers to just one and mitochondria is plural. Glucose: Also known as blood sugar, a simple sugar broken down in cells to produce energy. The possible inclusion of commercial websites below is not an implied endorsement of their products, which are not free, and are not required for this lesson plan.
Throughout the lesson, assess student comprehension by asking questions about the function of cell respiration and the differences between cell respiration and photosynthesis. Students relate the oxygen that is produced in photosynthesis to the process of respiration, in which oxygen is delivered to the cells of living things.
Then, students compare the processes of cell respiration and photosynthesis. Students will access prior knowledge of photosynthesis and respiration breathing from the previous two lessons. Students will carry out a kinesthetic activity to compare cell respiration and photosynthesis and also conduct an interactive simulation of the two processes online.
Students express their understanding during the kinesthetic activity and also by completing the handout throughout the lesson. The vocabulary from the lesson can be reinforced with a matching activity.
The lesson can be extended by having students research aerobic versus anaerobic respiration, or research the steps of aerobic respiration in detail. The lesson is organized so that students begin by accessing prior knowledge about photosynthesis and respiration breathing. The two meanings of respiration are explained. Then, students learn about the process of cell respiration and compare it with photosynthesis. Part 1: What is Cell Respiration? Begin the lesson with a review of the photosynthesis reaction.
Write the equation on the board and have students individually complete it in their notes:. Ask students why we need green plants and other living things that carry out photosynthesis for life on Earth. Elicit that green plants provide the oxygen we need in our bodies to release energy in cells.
Explain that the term respiration has two different meanings in life science. First, respiration is breathing, the process by which an organism takes oxygen into its body and then releases carbon dioxide from its body. Second, respiration also refers to the chemical reactions within cells by which food is burned and converted into energy, carbon dioxide and water. To distinguish from the first meaning of respiration, this burning of foods is also called cell respiration.
The blood delivers glucose to our cells. In the cells, cell respiration is the process of combining the simple sugar glucose with oxygen to form the energy-rich compound adenosine triphosphate ATP. Cells use ATP to carry out most of their functions, such as growing, producing new cell parts and chemicals, and moving compounds through cells and the whole body. Show students a diagram of a mitochondrion and tell them that this is where cell respiration takes place.
On the handout, have students sketch the mitochondrion and label its parts i. Describe the process of aerobic cell respiration in the mitochondrion.
Give an overview of the process, without going into detail about the specific reactions such as glycolysis and the electron transport chain. Have students write the reaction for cell respiration on the handout:. Then, have students write out the reaction in sentence form:.
Part 2: Comparing Cell Respiration and Photosynthesis. If computers with Internet access are available, have students work in groups to do the Illuminating Photosynthesis interactive simulation see Related Resources section , which illustrates the relationship between cell respiration and photosynthesis. Have students conduct the following kinesthetic activity to compare cell respiration and photosynthesis.
Have seven volunteers stand side-by-side at the front of the classroom. Distribute the construction papers labeled with the reactants and products of cell respiration and photosynthesis. Display the Cell Respiration side of the poster board and have students help the volunteers arrange themselves in the correct order to show the reaction.
Then, display the Photosynthesis side of the poster board and have students help the volunteers rearrange themselves in the correct order to show the reaction. Ask students what this demonstration is showing i.
Tell students that plant cells conduct both photosynthesis and cell respiration and ask them why plant cells need respiration, too.
For students who may need opportunities for additional learning, provide sentence strips that they can arrange to complete the T-chart on the handout.
Students who require an extra challenge can research the processes of aerobic and anaerobic cell respiration and create a Venn diagram to compare them. Alternatively, have them research the three steps of aerobic cellular respiration i. You are impersonating.

This video clip discusses the need for the students to see the "BIG picture" of how photosynthesis and cellular respiration function in the macro-scale of the Carbon Cycle. Students will need to determine if each statement describes photosynthesis, cellular respiration, or both. Students will record their responses on their paper to reference during our pair-share and class discussion. Students will share their answers with their neighbor and identify two statements that were most confusing. The class will discuss these "hang-up" statements in detail to ensure clarification before the lesson moves forward.
