  1. Unit 1: Plants Bio and Life Sciences Applied Critical Science Ms. Sara J. Ball

  2. What do plants need? • Let’s make a list of what plants need: • Water • Sun • Soil • Nutrients/Food

  3. Where do these needs come from?

  4. Life Cycle of a Flowering Plant • Vocabulary to Know: • Germinating: when a seedling comes up. • Pollinating: when pollen goes from an anther (male) to a pistil (female). • Stamen: The lengthy stem holding the anther out for pollinators to reach. • Pistil: the part of the flower that holds the ovary. • Ovary: where the eggs are contained in a flower. • Pollen: the seed that fertilizes the egg in a flower. • Seedling: the first sprout that germinates from a seed.

  5. Parts of a Flower Vocabulary

  6. Life Cycle of a Flowering Plant Germinating Pollinating

  7. Life Cycle of a Flowering Plant • Pollination: 3 Methods- • Self-pollination: plants can use their own pollen to fertilize their flowers. • Natural pollination: the wind or animals transfer pollen from anthers to pistils • Cross-pollination: plants of one kind can pollinate plants of another kind.

  8. Life Cycle of a Flowering Plant • Seeds have three parts: • Embryo • Food (cotyledon) • Seed coat • Once seeds find water, space and sun, they germinate.

  9. Life Cycle of a Flowering Plant • Create your own Mini Book about the life cycle of a flowering plant using the Mini Book 2 template worksheet. Each page should contain a picture of the stage in the life cycle and a label. • Number your pages. • Cut out your pages. • On the back of each page write one sentence about what happens in that stage. • Staple your Mini Book together on the left hand side to make a book.

  10. Parts of a Flower Vocabulary

  11. Parts of a Flower Vocabulary

  12. Name the Parts of a Flower

  13. Do you see the petals and leaves? petals leaves

  14. Do you see petals, anthers and pistils? petals anthers pistil

  15. Do you see petals and anthers? petals anthers

  16. Do you see petals, anthers and the stem? petals anthers stem

  17. Do you see petals, a stigma and the stem? petals stigma stem

  18. Do you see petals, anthers and the stigma? petals anthers stigma

  19. Do you see the ovaries? Ovaries (fruit)

  20. Do you see the ovaries? Ovaries (fruit)

  21. Do you see the pistil, ovary, stigma and anthers? stigma anthers pistil ovary

  22. My Flower- Spinach! pistil stigma petals anthers

  23. Parts of a Flower • Work in your seed groups and use the Internet to find pictures of the flower that your plant produces. • On a sheet of drawing paper, make a careful drawing of your plant’s flower. Notice the colors and shapes of the flower. • On your drawing, labels the parts of the flower, identifying the parts that match the picture of a flower in our notes. • Color your picture so the flower is the correct color for your plant.

  24. Plant Cells • Vocabulary to Know: • Cell Wall: the cellulose wall surrounding the cell. • Cell Membrane: • Mitochondria: • Vacuole: • Nucleus: • Cytoplasm: • Choloroplast:

  25. Plant Cells Cell Membrane Thin skin on the outside of a cell that allows nutrients and waste to pass in and out of the cell.

  26. Plant Cells Mitochondria Create the energy used by the cell every day. “Powerhouse of the cell”

  27. Plant Cells Cell Wall Firm structure and support for the cell. Protects the cell membrane.

  28. Plant Cells Vacuole Contains water or waste products of the cell. Storage closet for the cell.

  29. Plant Cells Nucleus The “brain” of the cell. Contains the DNA and controls everything in the cell.

  30. Plant Cells Chloroplasts Contain chlorophyll, conduct photosynthesis, store food for the cell.

  31. Plant Cells Endoplasmic Reticulum The “stomach” of the cell, digests carbs and fats. Also, the “post office” of the cell, packaging things up and shipping them out!

  32. Plant Cells Ribosome Make proteins for the cell to use.

  33. Plant Cells Cytoplasm The “jelly” in which the other organelles exist and do their things!
