EQ: WHAT ARE THE COMPONENTS OF PHOTOSYNTHESIS?

Things to think about: What is the sun’s role in photosynthesis? 2. What type of energy conversion occurs in photosynthesis? 3. What are the reactants and products of photosynthesis? 4. Why is photosynthesis necessary to life on Earth? 5. How can photosynthesis be observed? READ ONLY

Photosynthesis Process where radiant energy (from the sun) is used to turn water and carbon dioxide into chemical energy (glucose). Oxygen is a plant’s waste product that is released during this process.

Formula for photosynthesis Copy the full formula, with compounds and names

Question: Is photosynthesis a physical or chemical reaction? READ ONLY Is photosynthesis a physical or chemical reaction? Physical Change Chemical Change Changes size/shape Permanent Dissolves Creates a new substance Changes phase Gas production (bubbles) Unexpected color change Temperature change

Answer: Photosynthesis is a chemical reaction because it creates new substances Oxygen and Glucose (sugar) are NEW substances, the PRODUCTS of photosynthesis

Chloroplasts Chlorophyll are the organelles of a plant cell WHERE photosynthesis occurs. Chloroplasts are in plant cells ONLY (plants can photosynthesize while animals cannot) Chlorophyll is the chemical in chloroplasts that give plants their green color.

Each plant cell has NUMEROUS chloroplasts. Read Only

Stoma Openings/spaces on the undersides of leaves that allows gas exchange. This allows Carbon Dioxide to enter the leaf and allows Oxygen to be given off as waste) The problem is that the air spaces in the leaf are saturated with water, which exits the leaf through the stomata. Therefore, plants cannot gain carbon dioxide without simultaneously losing water. Read Only

Why is photosynthesis important to us? Consumers get their energy from eating producers 90% of ALL oxygen on Earth is produced through Photosynthesis

Answer the following in a complete sentence: If there wasn’t photosynthesis, there wouldn’t be plants. Therefore, what would happen to animals and plants? Why? Sentence Starter: If there wasn’t photosynthesis ______________ ______________________________________ would happen to plants and animals because ______________________________________

Reactants and Products REACT TO START A REACTION PRODUCTS ARE PRODUCED (made) during a reaction LABEL THE REACTANTS AND PRODUCTS IN THE PHOTOSYNTHESIS FORUMULA
