2. SC-04-3.4.1 Each plant or animal has structures that serve different functions in growth, survival, and reproduction.

3. SC-04-3.4.3 Plants and animals have life cycles that include the beginning of life, growth and development, reproduction and death.

4. Ideas Plants are made up of different parts. Each part has a certain job. These parts can also help us to identify plants. There are seven basic requirements that plants need in order to grow properly.

5. Plant Basic Needs Room to grow Temperature Light Water Carbon dioxide (air) Nutrients Time

6. Vocabulary Plant Structures – “parts of the plant” –Ex. Leaves, root, stem, flower, seeds, fruit Leaves – help the plant make food through a process known as photosynthesis. Root – help hold the plant in place and take in water and nutrients the plant needs. Stem – supports or holds up the plant. Flower – helps the plant reproduce. Seeds – are made from flowers when plants reproduce. Fruit – the edible part of a plant which contains seeds.

8. Roots

9. Roots Functions Most roots grow in soil or water. The roots hold the plant in the ground. A plant uses its roots to get water. The water goes through the roots into the plant. Some roots that we eat are: carrots, beets, turnips, radishes, and sweet potatoes.

10. Stems

11. Stem Functions The stem is the part of a plant between the roots and the leaves. The stem holds up the plant. The stem also carries water and food through the stem to the plant. Some stems that we eat are: celery, broccoli, asparagus, white potatoes, and sugar cane.

12. Leaves

13. Leaf Functions A leaf grows on the stem or branch of a plant. A green plant makes food in its leaves through a process known as photosynthesis. The leaf has tiny holes that let water vapor and air pass through. The leaves need sunlight, air, and water to make the food for the plant. Some leaves that we eat are: lettuce, brussel sprouts, spinach, and parsley.

14. Fruit and Seeds

15. Fruit and Seed Functions Seeds are made from flowers. Many plants grow from seeds. Fruits hold seeds. Some fruits that we eat are: tomatoes, oranges, pears, watermelon, and strawberries

19. Structures of a Flower

20. Flower Functions Flowers grow on the stem of plants. Flowers make seeds. Many plants grow from seeds. Flowers make fruits. Fruits hold the seeds of the plant.

21. Lets see what you learned… Draw a plant. Label its structures. Explain the function of each structure. Don’t forget to tell how the function contributes to the growth, survival, or reproduction of the plant. Draw a flower. Label its structures. Explain the function of each structure. Don’t forget to tell how the function contributes to the growth, survival, or reproduction of the plant.

22. What Am I ? Using the vocabulary worksheet, help your partner learn the names of plant parts by giving clues. For example, “I take in water and minerals from the soil. What am I ?” Give your partner one clue for each vocabulary word. Once you have completed the list with your partner, switch.

23. Identification Draw and label the following parts of a plant. Leaves Roots Flower Fruit Seeds Stem
