  1. The Life Cycle of a Plant Third Grade Plant Science

  2. Sadie the Seed Hi I am Sadie the seed and I will guide you along in the lesson, The Life Cycle of a Plant. Whenever you see me on your screen just click on me and I will help you out! Are you ready to get started? Just press the arrow!

  3. What we are studying and why? Today we are going to be studying the life cycle of a plant. Plants are a vital part of our every day lives. They provide nutrients, herbs, food and much more. It is important we realize plants are constantly changing and that we are able to identify those changes. Teachers

  5. Seed Dispersal There are many kinds of seeds and each grow a different kind of plant, but where do seedscome from? Menu

  6. Seed Dispersal The fruit of a plant grows during the spring and summer, like this apple tree shows. The seeds grow in the fruit of the plant. Menu

  7. Seed Dispersal Plants become dormant during the fall and winter months. There are a number of ways that the seeds can leave the plant. Menu

  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

  35. Plant Growth If you have questions about the plant life cycle, try going through parts of the lesson again or ask your teacher. If you know the material, you can move on to the review. Keep upthe good work! End of section Click on menu Menu

  36. Review Great work! You have now gone through the whole lesson and it is time to reviewfor the quiz. Menu

  37. Review Here is a video to show clearly how theplantcycle occurs. End of section Click on menu Menu

  38. Quiz Are you ready for the Quiz? There will be 10 questions over the plant life cycle. If you do not feel ready, review the lesson again then come back. If you are ready click the arrow and good luck! Menu

  39. Quiz Directions: Answer the questions to the best of your ability. If you need to stop and review the material again, simply click the menu button and try the quiz again when you feel better prepared. If you are ready now, click the forward arrow. Menu

  40. Quiz • When a plant becomes dormant what happens next in the life cycle? A)The life cycle ends B) Nothing happens C) The life cycle begins again in the Spring Menu

  41. Quiz Good try but take another shot.

  42. Quiz Something is always happening in the plant life cycle, try again.

  43. Quiz Correct! A plant life cycle never stops, the plant just grows at a slower rate when dormant and begins growing faster whenspring begins.

  44. Quiz 2) What does a plant need in order to grow? A) Water B) Air C) Sunlight D) Soil E) All of the above Menu

  45. Quiz Close, but try again.

  46. Quiz Air is very important but something else is needed too.

  47. Quiz Nice try but it is not the right answer.

  48. Quiz Soil provides nutrients but it is not the correct answer.

  49. Quiz Good work! All of these are needed to make a plant grow.

  50. Quiz 3) Where do seeds come from? A) The ground B) The plants fruit C) The store D) None of these Menu
