Humans, animals and plants depend on the cycle of cellular respiration and photosynthesis for survival. The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. The carbon dioxide produced during respiration is released from the body and absorbed by plants to help provide the energy they need for growth and development.
This is the never ending cycle that sustains life on earth. The process of photosynthesis is used by plants and other photosynthetic organisms to produce energy, whereas the process of cellular respiration breaks down the energy for use. The structure of xylem and phloem in a plant is analogous to arteries and veins in humans, which move blood to and from the heart and lungs. For more information regarding the structure and function of xylem and phloem, review the Irrigation and Rootstock sections.
Leaves contain water which is necessary to convert light energy into glucose through photosynthesis. Leaves have two structures that minimize water loss, the cuticle and stomata. The cuticle is a waxy coating on the top and bottom of leaves which prevents water from evaporating into the atmosphere Figure 3a. Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in to be used in photosynthesis , and oxygen out.
These gases move into and out of the leaf through openings on the underside called stomata Figure 3b. Respiration Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes.
Respiration occurs when glucose sugar produced during photosynthesis combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration Figure 4. Figure 4. Simple equation describing the molecules required for respiration and its products.The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is. And plants evolved in the tropics and are adapted plants need carbon dioxide, water, and sunlight to carry at higher photosynthesises. Objectives Through this kinesthetic respiration, students will learn: that to higher temperatures than are the C-3 plants found out photosynthesis.
Background for Teachers Photosynthesis is an essential process in plants. Water must also be carried to the cell. In this activity, students will act out both processes photosynthesis and cellular respiration , providing a tangible illustration of what components are needed for each process, as well as what the waste products are. These electrons can create an electrical current. Specifically, six molecules of carbon dioxide and six molecules of water yield one molecule of glucose, with six molecules of oxygen given off as a by-product. Review or introduce the concept of stomata, which are small openings on the underside of the leaf.

Only fetch one thing at a time. You will need 6 egg cartons for each group. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures, diffusing into the cells. Home Photosynthesis and Respiration Photosynthesis and Respiration The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. The breakdown of carbon dioxide and water molecules in the cell results in the formation of sugar molecules.
This will be the very same process as it was for plants—the only difference is that oxygen enters through the lungs instead of the stomata. Tell students the scenario, remove access to one resource, and let them try to produce a sugar molecule. Give groups empty CO2 and H2O frames.
Animals are carbon dioxide producers that derive their energy from carbohydrates and other chemicals produced by plants by the process of photosynthesis.
Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Some of the oxygen atoms will come from CO2 molecules and some from H2O molecules.
Simple equation describing the molecules required for respiration and its products. During respiration, plants consume nutrients to keep plant cells alive while during photosynthesis, plants create their own food. Determine how many groups you will have. Through this process, large molecules, such as the sugar molecules produced by photosynthesis, are broken down so that the energy stored within them can be used by the organism. Bring these molecules from the sink to the table.
