Plant Science Bundle 1
Photosynthesis and Cellular Respiration (#30S): This kit consists of two parts. In Part One, students investigate the reactions of photosynthesis and cellular respiration by organizing a series of images and statements. Students discuss the roles of each of these processes in an ecosystem and connect this information to the carbon cycle. In Part Two, they read about the details of photosynthesis and cellular respiration, including the light-dependent and light-independent reactions of photosynthesis, and the three stages of respiration— glycolysis, the Krebs cycle, and the electron transport chain.
Photosynthesis, Plants and Food (#31): In the opening activity, student teams use atom models to build carbon dioxide and water molecules then “react” them to form sugar and oxygen molecules. Students then read about plants’ essential role as producers, using the process of photosynthesis to convert carbon dioxide, water, and energy contained in light into energy stored in the bonds of sugar, and other food, molecules. They are also introduced to the plant organelles called chloroplasts that allow the production of carbohydrates, proteins and fats by using sunlight, carbon dioxide, and water.
Seed Staining (#66): In this engaging and fun kit, students learn how to differentiate between plant food stored as a simple sugar and food stored as a starch. Using a step-by-step procedure, students first dissect the seeds, and then treat them with reagents. This helps to determine the quantity and location of the sugar and starch. The individualized, open-ended worksheets provide additional investigations for student exploration.

Scientific Concepts
•Photosynthesis is a cellular process through which organisms capture light energy from the sun and use it to generate and store energy. Photosynthesis happens in the chloroplasts, which contain chlorophyll. Only producers can perform photosynthesis.
•Photosynthesis takes in light energy, carbon dioxide, and water, producing glucose and oxygen. Light is required for photosynthesis to occur, although parts of photosynthesis can happen in the absence of light.
•Cellular respiration releases stored energy in glucose, allowing the organism to function. Many organisms, including plants and plankton, perform oxygen-dependent cellular respiration. Cellular respiration happens in the mitochondria and cytoplasm of cells.
•Cellular respiration takes in oxygen and glucose and produces carbon dioxide and water. Adenosine triphosphate (ATP) is also produced from cellular respiration.
•The substances produced and consumed in photosynthesis and cellular respiration are complementary.
•Students develop conclusions based on evidence.
•Students make accurate interpretations, inferences, and conclusions from text.
•Cells carry on the many functions needed to sustain life.
•Specialized cells perform specialized functions in multicellular organisms.
•Plants and some microorganisms are producers-they make their own food.
•For ecosystems the major source of energy is sunlight.
•Most cell functions involve chemical reactions.
•Plant cells contain chloroplasts, the site of photosynthesis. Plants and many microorganisms use solar energy to combine molecules of carbon dioxide and water into complex, energy-rich organic compounds and release oxygen into the environment.
•The energy for life primarily derives from the Sun. Plants capture energy by absorbing light and using it to form strong (covalent) chemical bonds between the atoms of carbon-containing (organic) molecules. These molecules can be used to assemble larger molecules with biological activity (including proteins, DNA, sugars, and fats). In addition, energy stored in bonds between the atoms (chemical energy) can be used as sources of energy for life processes.
•The chemical bonds of food molecules contain energy. Energy is released when the bonds of food molecules are broken and new compounds with lower energy bonds are formed.
• Understand the difference between plant food that is stored as simple sugar and food stored as starch in sprouting seeds
• Dissect seeds and treat them with reagents
• Develop lab techniques
