The Lifecycle of a Plant 2 nd Grade

1. The Lifecycle of a Plant2nd Grade Sara Lubanski EDU 3460

2. Goals • The goal of this presentation is for you to become familiar with what plants need in order to grow as well as the different stages in the life cycle of a plant. • At the end of this presentation, there will be a three question quiz on the content learned. • In order to achieve the goal of this presentation, all three questions must be answered correctly.

3. Standards • Standards Addressed: • “L.OL.02.14 Identify the needs of plants.” • “L.OL.02.22 Describe the life cycle of familiar flowering plants including the following stages: seed, plant, flower, and fruit.” • These standards are part of the Michigan Grade Level Content Expectations (GLCE’s)

4. The Beginning of a Plant Click the flower to watch a video of a seed going through germination! [1] Back to Quiz Question 1 All plants start as seeds Seeds come in all shapes and sizes Seeds go through a process called germination Germination is when a plant starts emerging from a seed

5. What Does A Seed Need? In order to grow into a plant, a seed needs proper light, water, warmth, and minerals Without all of these things, a seed will not germinate

6. Parts of a Plant Once a seed grows into a mature adult plant, it has: Roots Stem Leaves Flower To help you remember the parts of a plant, click on the picture to listen to a silly song! [2]

7. Roots Provide support by securing the plant in the ground Absorb water and nutrients for growth • Two types of roots: • Taproot • Fibrous

8. Taproot I’m a taproot! Back to Quiz Question 2 Taproots reach far underground They have one main root with smaller roots branching off of it A common taproot that we eat are carrots

9. Fibrous Roots I’m a fibrous root! Fibrous roots are a bunch of very fine roots These roots are spread throughout the soil Common fibrous roots are grass and onions

10. Stem • Provide support, acts as the plants backbone • Carry water and nutrients from the roots to the leaves • Move food produced by the leaves throughout the plant • Two parts inside the stem: • Xylem cells – move water • Phloem cells – move food

11. Leaves • Make food for the plant through a process called photosynthesis • Come in many different shapes and sizes • Simple leaf – single leaf blade • Compound leaf – separate leaflets Simple Leaf Compound Leaf

12. What is Photosynthesis Back to Quiz Question 3 • How greenplants make their food • Chlorophyll is a pigment that makes some plants green • Chlorophyll is the main factor of photosynthesis • Carbon dioxide, water, and light energy are changed into glucose • Glucose is a sugar that is the source of food used by plants

13. More on Photosynthesis! Click the flower to join Mrs. Frizzle and Liz and learn more about photosynthesis! Check out The Facts, play the Factivity, and look at some of the Beyond the Facts websites! [3]

14. Flower • Flowers are used for more than just making a plant look pretty • Flowers are important in making seeds • The colorful petals of flowersattract pollinators, such as bees and butterflies • Pollinators move seeds from place to place, and help new plants to grow!

15. Fruits Some flowering plants also contain fruits Fruits carry seeds and help plants to keep growing When the seeds are dispersed, they can get buried After they’re buried, if given proper light, water, warmth, and minerals the cycle starts all over again!

16. Video Time! Hey Second Graders, click the flower to learn more about the parts of a plant and their functions! [4]

17. Why Are Plants Important? Plants are an important part of every habitat. Humans and animals use plants as a source of food! Many medicines come from plants Plants help control the water cycle Through photosynthesis, plants take in the carbon dioxide we breathe out, and release the oxygen that we breathe in. We balance each other out!

19. Checking for Understanding It’s time to see what you’ve learned! This quiz has three questions. Each question has four answers to choose from. If you get the question correct, you can move on to the next one. If you get the question incorrect, you can go back to another slide to refresh your memory. Then you can try answering the question again! Good luck!

20. Quiz Question 1 What is the process a seed goes through to become a plant? Precipitation Photosynthesis Germination Flowering

21. Correct! GoodJob!

22. Quiz Question 2 What is a common type of taproot? (Remember, taproots have one main root with smaller roots coming off it) Grass Carrots Dandelions Onions

23. Correct! Well Done!

24. Quiz Question 3 What is NOT used by a plant to make glucose during photosynthesis? Sugar Carbon Dioxide Water Light energy

25. Correct! You Got It!

26. Congratulations! You have completed the quiz and now you know all about plants! Plants are an important part of our world. Now that we know about the parts of a plant, we will be growing and observing our own!
