4. Plants Plants are an important part of our environment. Without plants, animals and human beings could not survive. Think of a few ways we, as humans need plants…

5. Plants produce us with: food oxygen medicines building materials seasonings candy &drinks industrial products dyes & decorations manufactured good paper

6. Plants are producers Plants are the only living thing able to make their own food. There are a few things plants must have to survive… What do you think those things are?...

7. THE SUN: MAIN SOURCE OF ENERGY FOR LIFE ON EARTH

8. Water

9. Soil

10. Carbon Dioxide

11. In order to grow, green plants use sunlight and store its energy in their leaves and stems. Sunlight enables plants to convert water into foods needed by the plant. Plants also need carbon dioxide, which all animals (including humans) give off as they breathe. This remarkable process is called: Photosynthesis

12. Photosynthesis (put in notes) Plants need food and can make their own food. Green plants need 1. carbon dioxide from the air 2. water and minerals from the soil 3. energy from the sun

14. Photosynthesis

16. Photosynthesis is the process by which plants use sunlight to make energy/sugar and oxygen from carbon dioxide and water AN OVERVIEW OF PHOTOSYNTHESIS Carbon dioxide WaterGlucoseOxygen gas PHOTOSYNTHESIS

17. Energy for plants (notes) The water and carbon dioxide combine into sugars and oxygen. Sugars are the food for the plant. Plants use some of the sugars to grow, and store the rest in their tissues. When you eat a plant, you take in energy the plants stored.

19. Let’s review What do plants need to make their own food?

20. Plants need water Water helps the seed germinate The plant grows

21. Plants need the sun The sun gives the plant warmth The sun gives the plant light to help it make food

22. The plant needs minerals The plant gets minerals from the soil to make it grow strong and healthy

23. The end result

24. EQUATION FOR PHOTOSYNTHESIS 6CO 2 + 6H 2 O + ENERGY C 6 H 12 O 6 + 6O 2 CARBON DIOXIDE WATER GLUCOSE OXYGEN

25. There is one cell structure that allows plants to conduct photosynthesis Think of a cell part that plants have and animals do not…

26. (a) Mosses, ferns, and flowering plants (b) Kelp (c) Euglena What is one thing all of these plants have in common? They are all green!

27. WHY ARE PLANTS GREEN? It's not that easy bein' green Having to spend each day the color of the leaves When I think it could be nicer being red or yellow or gold Or something much more colorful like that… Kermit the Frog

28. Why are plants green? Think back to the parts of a plant cell…

29. WHY ARE PLANTS GREEN? Plant Cells have Green Chloroplasts The thylakoid membrane of the chloroplast is impregnated with photosynthetic pigments (i.e., chlorophylls).

30. Chloroplats Chlororplasts contain pigments that absorb sunlight. They use the energy to make food in a process called photosyntheis.

31. Put in notes Chloroplasts are the only organelles that can perform photosynthesis. The pigment chorophyll gives plants their green color.

32. It's not that easy bein' green… but it is essential for life on earth!

33. Why is photosynthesis important for life to exist? Every ecosystem is dependent on photosynthesis. Remember! The process of how plants make their own food is photosynthesis.

34. Homework Draw a picture to represent photosynthesis. Under the picture write what is taking place.
