• What is photosynthesis?


  A chemical reaction that occurs in the chloroplasts of plants
• What is the role of chlorophyll in photosynthesis?


  It enables the process of photosynthesis to occur by absorbing light energy
• What are the main products of photosynthesis?


  Oxygen and glucose
• What do plants need for photosynthesis to take place?


  Carbon dioxide, water, and light energy
• Where does photosynthesis take place in plant cells?


  In chloroplasts
• How do plants obtain carbon dioxide and water for photosynthesis?


  Carbon dioxide from the air through leaves and water from the ground through roots
• What is the word equation for photosynthesis?


  Carbon dioxide + water → glucose + oxygen
• Why is photosynthesis important for life on Earth?


  It provides oxygen needed for respiration and is essential for food chains
• How does photosynthesis contribute to the balance of gases in the atmosphere?


  It decreases carbon dioxide concentration and increases oxygen concentration
• What are producers in a food chain?


  Organisms that make their own food through photosynthesis
• What happens to the glucose produced during photosynthesis?


  It can be used for energy, stored as starch, or converted into fats and oils
• What is cellulose and its significance in plants?


  Cellulose is a polymer made from glucose that provides strength to plant cell walls
• How do plants store energy produced during photosynthesis?


  As starch, which can be converted back to glucose when needed
• What is the role of glucose in plants?


  It is used for energy and as a building block for carbohydrates
• What is the relationship between jellyfish and photosynthetic algae?


  Jellyfish host algae that perform photosynthesis, providing glucose for the jellyfish
• How do jellyfish adapt to maximize photosynthesis?


  They swim towards the sunlight and adjust their position throughout the day
• What are the uses of glucose produced in photosynthesis?


  To release energy, make cellulose, starch, fats, and amino acids
• What is the significance of the relationship between plants and animals in the ecosystem?


  They depend on each other for oxygen and carbon dioxide balance
• How does decomposition contribute to the carbon cycle?


  It releases carbon dioxide back into the atmosphere
• What is the impact of photosynthesis on fossil fuel formation?


  Fossil fuels are formed from the breakdown of ancient plants that underwent photosynthesis
• What are the main components of a plant cell involved in photosynthesis?

  Chloroplasts and chlorophyll
• Why do plants only photosynthesize during the day?


  Because they need sunlight to perform photosynthesis
• How does the process of respiration relate to photosynthesis?


  Respiration uses glucose and oxygen produced by photosynthesis to release energy
• What is the role of nitrate ions in plants?


  They are absorbed by roots to help make amino acids
• What is the significance of fiber in human diet derived from cellulose?


  It assists the digestive system by keeping food moving through the gut
