SEEDS

1. What do you think these are pictures of? SEEDS

2. Where can you find seeds? Seeds are everywhere…... In our backyards In our food

3. What will these seeds become? Oak Tree Acorn Coconut Tree Coconut

4. What will these seeds become? Maple Tree Pea Plants Peas

5. What is the Function of a seed? • Nourishment:The seed provides food for the young plant while it is developing the parts it needs to make its own food. • Seed Dispersal: The design of the seed helps the seed travel to other places to germinate.

9. Part 2Structures of a Plant

10. Functions • Keep the plants in place • Absorbs water and nutrients from the soil • Some roots help the plant by storing food. Roots

11. Types of Roots • Taproots • Large • Grow deep into the soil. • Are able to store food. • Fibrous Roots • Thin and stringy • Lie close to the surface • Can often be found growing side by side with taproots. • Adventitious Roots • Strong and can be thin or thick. • Develop to help the plant climb • Found in ivies and vines

12. Functions: • Supports the plant and gives them shape. • Contain small tubes: • Xylem carries water and minerals from the roots • Phloem: carries food that is made in the leaf to the rest of the plants. Stem

13. Where plants make their own food in a process called photosynthesis. • Many kinds of leaves • Needles • Broad Leaves Leaves

14. Found on most conifers and cacti. • They do not shed their needles in the Fall. • Their shape helps prevent water loss. Needles

15. Leaves can be found in all shapes and sizes based on their environment. • In cold climates plants shed their leaves because there is less sunlight for photosynthesis to take place and the plant needs to save its energy. Broad Leaves

16. Leaves are the factory of the plant where food is made in a process called photosynthesis. http://vimeo.com/1616728 Click link to view video

17. A process plants use to make their own food • Plants’ leaves contain chlorophyll • Chlorophyll (green color) makes photosynthesis possible What is photosynthesis?

18. The chlorophyllabsorbs and traps the sunlight or energy from the sun.

19. The sunlight is combined with water and nutrients from the soil that has been absorbed by the roots. • Carbon Dioxide exhaled by animals is also absorbed by the leaves

21. When the process of photosynthesis is complete, the plant has made 2 things.: Sugar : The food the plant has made for itself Oxygen: A waste that is released by the plant that we need to survive. Oxygen Oxygen Oxygen

22. Animals and plants need each other to survive. • Plants give animals oxygen to breath and live. • We give plants carbon dioxide to make food.

23. What is transpiration? • Water is absorbed from the roots of a plant and travels to the leaf. • The sun heats the water in the leaf turning the water from a liquid to a gas called water vapor • The water is released into the air through tiny holes called stomata Transpiration also takes Place in the Leaves of a plant http://www.youtube.com/watch?v=At1BJJDcXhk&feature=related

24. What is the function of the flower in a plant? • Attract insects and animals using bright colors and wonderful scents. • Produce or make the fruit and seeds of the plant Flower

25. Parts of a Flower

26. The stamen is the part of the flower that makes pollen. • Pollen is fine powder needed for pollination. Stamen

27. Pistil • The pistil is made up of 3 main parts: • Stigma • Collects pollen • Style • Separates the stigma from the ovary • Ovary • Where the fruit/seeds form. Pistil

28. What is pollination? • Pollination is how seeds are formed to create a new plant. • Pollination occurs when pollen from the anther on the top of the stamen is carried to the stigma on the top of the pistil. • The pollen travels down the pistil through the style to the ovary • There the pollen fertilizes an ovule and a new fruit/seed is formed Pollination http://videos.howstuffworks.com/hsw/9756-our-flowering-world-flower-parts-video.htm

29. Insects and animals are important participants in Pollination http://www.youtube.com/watch?v=ge3EM8AERV0

30. Can you put the pictures in order to show the life cycle of a Seed plant Teachers' Domain: Life Cycle of a Seed Plant

31. What are spores? • Spores are tiny, seed like spots on the underside of certain plants like ferns. • Spores contain stored food and will fall of the plant and germinate(grow)if the conditions around them are right. Some plants use Spores to reproduce

32. Bulbs • A type of bud that grows underground. Tulips grow from a bulb. • Runners • Some plants can grow from the stem of an older plant. A spider plant can reproduce this way. There are other ways plants can reproduce

33. Grafting • Combining two different plants to create a new and better plant. You can attach one apple tree to the trunk of another apple tree to make a better tasting apple There are other ways plants can reproduce

34. Tubers • Are swollen underground stems. • We often eat them. • Tubers develop “eyes” that will develop into a new plant. There are other ways plants can reproduce
