1. Is there evidence that plants make, use and store foods?

2. Ahhhhh but yes! Plants use Carbon Dioxide and Water to make Glucose - It’s Photosynthesis Let’s examine……………………..

3. carbon dioxide CO 2 ‘photo’ = LIGHT ‘synthesis’ = BUILD chlorophyll Photosynthesis means building with Light + water H 2 O glucose C 6 H 12 O 6 + oxygen O 2  Green plants can make their own food from ……..… and ………..…  using energy in the form of ………………….  which is absorbed by chlorophyll in the ………………...  The end products of photosynthesis are ………. and ………….

4. 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

5. The glucose is very useful for the plant Can be used in respiration to release energy can be joined together to make starch for storage Can be converted into fats and oils for the seeds Can be joined together to make cellulose for the cell walls Can be combined with nutrients from the soil to make proteins for the new growth Can be converted to fructose for the fruit

6. 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).

7. 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.

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

9. Evidence…..Because of its stored (food) energy, the potato continues to grow long after it has been harvested.

10. 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.

11. Roots also store food – their location underground is utilized by many plants as a place to store food out of the reach of the typical herbivore for times of the year when conditions are not suitable for growth. Storage Roots

12. Explain the process (give evidence) of how plants make, use, and store food. Now, add this to your “I can statements” It’s your turn…..
