Energy in Everyday Life Q1) Where do you get your energy? Food Q2) Where do birds and squirrels living outside in our neighborhood get their energy? Insects and nuts Q3) Explain why this statement is true: “All the energy starts from the sun.” Sun gives energy to plants to grow. Animals including humans eat plants. Q4) What is the process where plants take the sunlight and change it into energy? Photosynthesis Q5) What other two types of organisms also can change sunlight into their own energy? Bacteria and algae Q6) Where does the energy for life come from? __________Sun_______ Q7) In addition to foods, what other resource (material) do plants give us and other living things to live? _______Oxygen________ Q8) In photosynthesis, the reactants are: _____Water______, _Carbon Dioxide________ and the products are: _____Oxygen_____________________, ___________Glucose (sugar)________ Q9) Glucose is sugar that has the chemical formula of: ____C6H12O6_________ Q10) What chemical is not part of the photosynthesis process? __________Carbon Monoxide______ Q11) What is one thing do you remember about ‘cells’? Cells are small things that make up all living things. Q12) What structures do you find inside of every cell? ____Organelles_______ Q13) What particular organelle will we be focusing on for the study of photosynthesis? _____Chloroplast______ Q14) What organelle found in the leaf cells does photosynthesis take place? Chloroplast Q15) What is the job of the chlorophyll found in the chloroplast? Chlorophyll capture sunlight Q16) How do plants take in the two reactants, water and carbon dioxide? Take in water through roots. Take in carbon dioxide through stomata. Stomata are holes found underneath leaves. Q17) Which of the following are used in Photosynthesis? (3 answers) Water, sun and carbon dioxide Q18) Which plant parts are used in the collection of raw materials for photosynthesis? ______roots and stomata (found in leaves)___ Q19) Which step collects the raw materials? ____Step 1____ Q20) In which step does the chemical reaction take place to produce glucose (sugar) and oxygen? _______Step 2_____ Q21) Why is the Step 2 called, ‘dark reaction’? It does not need sunlight to work. Q22) Why is the second process (dark reaction) in Photosynthesis also called the Calvin Cycle? Dr. Calvin discovered the second step of the photosynthesis Q23) What is the name of the cycle that is also known as the light independent reactions? ___Calvin Cycle__ Q24) Why is Calvin Cycle also called dark reactions? It does not need sunlight to work Q25) What is the chemical equation for the photosynthesis? Carbon dioxide + Water  Oxygen + glucose (sugar) Q26) What are two products of photosynthesis? Oxygen and glucose
