  1. Plant Structure Unit Mrs. Krajewski

  2. Plant Characteristics Plant Cells

  3. Plants are made a small building blocks called cells. Different parts of a cell do different jobs. • Ex: some cells may have the job of making food for the plant • All plants are made up of cells. CELLS: Make up a plant. Cells are organized into tissue and tissue is organized into organs. CELLS

  4. What do plants need to survive?

  5. Plants need: Sunlight Water Carbon dioxide Minerals from the soil

  6. Make a 4 fold!

  7. Plant Habitats: • Plants live in many different habitats. Some can survive in extremely cold or hot weather. Some plants such as lilies can grow in water by using the soil at the bottom of a pond! Habitats

  8. Photosynthesis Chorophyll • The process of making the sugar, which is the food the plant needs to survive. • Plants make their own food! • Let’s read pages 48 and 49! • Photosynthesis takes place in chloroplasts of leaf cells. • Chloroplasts contain chlorophyll. • “chloro” is a Greek word for “green”. Chlorophyll makes plants green in color. • Chlorophyll captures energy from sunlight.

  9. Check Point Questions: • What are the 3 characteristics of plants? • In what part of a plant cell does photosynthesis occur? Questions – Text p. 49

  10. Parts of a Plant

  11. The Main Parts of a Plant: Roots Stems Leaves

  12. Roots: Grow downward in the soil. • Function: 1. absorb water from the soil. 2. absorb nutrients from the soil. 3. hold the plant in place 4. roots in some plants store food. Roots

  13. Types of Roots • Taproots have one lard root (ex: dandelions, carrots, and parsnips). • Fibrous Roots spread out and no one root is larger or important than another. • Root Hairs: threadlike cells on a root that take in water and minerals. Most roots have root hairs.

  14. Tap Roots

  15. Fibrous Roots

  16. Root Hairs

  17. Stems

  18. What is a stem? A stem grows above ground level. • What is its function? • Carry water , minerals, and nutrients from the roots to the leaves. • Support leaves and flower. Stems

  19. Types of Stems 1. Woody Stems: Are found in larger plants to give the plant extra support. Woody Stems Soft, Green Stems

  20. Types of Stems 2. Soft, Green stems: Are found in smaller plants like the strawberry plant or daisies. Woody Stems Soft, Green Stems

  21. Leaves

  22. What is a leaf? The main food-making part of a leaf. • Main Parts: • Veins • Epidermis • Chlorophyll • Stomata Leaves

  23. Veins: are bundles of tubes that carry water to the leaf and food from the leaf to the stem and roots. • Epidermis: is the protective layers that keeps the leaf from drying out and losing water. • Chlorophyll: is a green substance which traps the sun’s energy; which is used to make food. • Stomata: are tiny openings on the bottom side of the leaf, which allows gas and water vapor to pass in and out. Veins, Epidermis, Chlorophyll, and Stomata

  24. Leaves

  25. Types of Leaves: Pinnate Leaves Palmate Leaves

  26. Pinnate: Have parallel veins (running the same direction). Example: grass, corn, tulips, and onions. Pinnate Leaves

  27. GRASS LEAVES ONION LEAVES TULIP LEAVES Grass, corn, tulips, and onions. CORN LEAVES

  28. Palmate: Have veins that branch out from the center of the leaf. Ex: maple, rose, and poinsettia leaves. Palmate Leaves

  29. MAPLE Maple, rose, or poinsettia? POINSETTIA ROSE

  30. PINNATE LEAVES PALMATE LEAVES What type of leaf is it?

  31. PICK A STATE FIND THE STATE FLOWER WRITE ONE FACT ABOUT THE STATE FLOWER DOES IT HAVE PINNATE OR PALMATE LEAVES? PRINT OR DRAW A PICTURE homework Relate to Social Studies

  32. Life Cycle of a Flowering Plant

  33. Cycle: Seeds Seedlings Mature Plant Flowers Fruit Seed

  34. Part 1 Seeds: an underdeveloped plant with stored food sealed in a protective covering, seed coat. Ex: coconut seed

  35. Part 2 Seedlings: the germination of a seed sprouting into a new, young plant.

  36. Part 3 Mature Plant: the plant has grown enough to produce its own seeds.

  37. Part 4 Flowers: the mature plant will produce flowers that will be pollinated by insects or wind.

  38. Part 5 Fruit: the ovary of some flowers will grow into fruit which surrounds the new seed. Ex: apples and peaches.

  39. Part 6 Seed: the ovary of some flowers become seeds or seed pods. Ex: apples and peaches.
