8. Dormant When a plant is dormant it is during the fall and winter months. At this time the plant is not dead, just slowly growing.

9. Seed Dispersal Windcan blow the seeds and spread them around. Menu

10. Seed Dispersal Seeds in a pod can also burstopen and be spread around in this way. Menu

11. Seed Dispersal Plants can also shakeseeds off the plant. Menu

12. Seed Dispersal Watercan carry the seeds to different areas. Menu

13. Seed Dispersal Seeds can be carried away if they get caught on something. Menu

14. Seed Dispersal Animalseat seeds and they can be dispersedin that way. Menu

15. Seed Dispersal Sometimes seeds can justfall and rollaway. Menu

16. Seed Dispersal There are many ways seeds can be dispersed, but no matter which way they leave the plant they will eventually begin growingin the ground. End of section Click on menu Menu

17. Seed Growth Now that we have learned how seeds are dispersed, it is time we discover how seeds grow into plants! Menu

18. Seed Growth First seeds are planted in the ground. Menu

19. Seed Growth Roots begin to grow helping the seeds get nutrients. A shoot (a small stem) starts to grow out of the seed and up towards the ground. Menu

20. Seed Growth When the shoot reaches the surface of the soil, it becomes a sprout. Menu

21. Seed Growth Water, air, sunlight and nutrients from the soil help the sprout grow and turn into a seedling. Menu

22. Seedling A seedling is a small plant with very few leaves.

23. Seed Growth The seedling is now a young plant and plant growth is now noticeable. Menu

24. Seed Growth Do you know the order of seed growth? If you are unsure, review this part of the lesson again. End of section Click on menu Menu

25. Plant Parts It is important that we can identify the parts of plants so we know how the plant grows and what the parts do. Menu

26. Plant Parts • Seed • Roots • Stem • Leaf • Flower • Shoot • Fruit Menu

27. Plant Parts Can you identify all parts of the plant? End of section Click on menu Menu

28. Plant Growth As a young plant grows into an adult it grows more leaves and becomes a healthierand larger plant. Menu

29. Plant Growth However, if plants do not receive proper care or have to live in unfit conditions they will notgrow as well. Plant Growth Menu

30. Plant Growth Next, the plant will grow flowers or bloomswhich will then eventually grow fruit. Menu

31. Plant Growth The fruit grows during the spring and summer months, and when ripened can be harvested by humans or animals. Menu

32. Plant Growth As we have already mentioned before, the fruit contains the seeds and when the fruit has been produced the seeds can begin to be dispersed. Menu

33. Plant Growth Once the seeds are dispersed, the plant begins to become dormant. This is the last stage in the life cycle. When spring comes, dormancy will end and thelife cycle willbegin again. Menu

34. Plant Growth See a corn plant grow by watching this video! Menu
