Plant Food Production: Photosynthesis and Storage

Discover the evidence that plants make, use, and store food. Plants use carbon dioxide and water during photosynthesis to produce glucose, which can then be converted into carbohydrates and fats. They also absorb minerals from the soil to make proteins. Animals gain energy and nutrients by consuming plants. Tests can be conducted to detect the presence of carbohydrates, fats, and proteins in plants. Plants utilize the food stored in seeds to grow roots, stems, and leaves. Plant structures such as seeds, roots, nuts, and fruits contain nutrients and calories, indicating food storage.

Presentation Transcript

  1. L.OL.07.63Evidence that Plants make, use and store Food Plants use Carbon Dioxide and Water to make Glucose - It’s Photosynthesis

  2. Evidence Plants make food • Plants produce glucose. • Glucose can be combined into larger molecules of carbohydrates and fats. • Carbohydrates and fats can add minerals from the soil to make proteins. • Animals gain energy and useful material by eating plants

  3. Evidence Plants make food • Tests can be done that indicate the presence of carbohydrates, fats and proteins like using the indicator iodine to detect starch (a carbohydrate).

  4. Evidence Plants use food • Plants that start from a seed use the food inside the seed to grow roots, stems and leaves. • The seed coat shrivels and falls off as the food is used up.

  5. Evidence Plants store food • Plant structures such as seeds, roots, nuts and fruits contain nutrients and have calories.

  6. Evidence Plants store food • As the plant matures, the size of the fruit, nut root and/or seed increases indicating food storage • Extra food is stored in the roots, leaves and seeds.

  7. Complete your I can statement: • Explain the process (give evidence) of how plants make, use, and store food.
