  1. The Plant Kingdom PART ONE

  2. The Plant Kingdom 4 General Characteristics: 1) Multi-celled organisms 2) Plants make their own food by photosynthesis 3) They have chloroplasts organelle where photosynthesis takes place chloroplasts- • they’re green because they have chlorophyll Chlorophyll- • the chemical that gives plants their green color • traps light energy for photosynthesis

  3. Chloroplast

  4. Chloroplast

  5. 4 General Characteristics Cont’d 4) Plant cells have cell walls (animal cells do not) cells walls • stiff cell walls give structure to each cell • also supports the plant • made of cellulose • have holes through which cells share cytoplasm & pass nutrients sugars, water, and hormones

  6. Photosynthesis: Prefix photo means: Light Root word synthesismeans: to make Photosynthesis - Process in which plants use water, carbon dioxide, and energy from the sun to make food • only occurs in the chloroplasts • releases oxygen

  7. What process is illustrated here? Photosynthesis 6CO2 + 6H2O + light energy = C6H12O6 + 6O2

  8. Products of Photosynthesis

  9. How are plants organized? PLANTS Vascular Nonvascular Seed Plants Seedless Plants Ferns & related plants Mosses & related plants Angiosperms Gymnosperms

  10. PLANTS Vascular Nonvascular 2 Main Types of Plants 1) Vascular Plants • broken into 2 more subgroups called: a) seedless plants b) seed plants 2) Nonvascular Plants • not broken into subgroups

  11. Vascular Plants plants that have tube-like cells in their roots, stems, & leaves that carry H2O and nutrients Vascular Plants- • Vascular comes from the Latin word “vasculum” which means “vessel” • they lose their leaves like a pet sheds • roots, stems, and leaves of a plant are all called organs

  12. Vascular Plants: 3 organs and their jobs Vascular Plant Organs:( roots, stems, & leaves) ROOTS- • anchors the plant into the ground • takes in H2O & nutrients directly from the soil STEMS- • carry water to all parts of the plant • holds the leaves up to the sunlight LEAVES- • place where all of the chloroplasts are located

  13. Vascular Plants: 2 Types of Tubes • vascular plants have 2 different types of tube-like structures inside them a) xylem b) phloem • each one has a specific function (job) • think of tiny pipes...like a plumbing system tube-like cells that carry water & dissolved minerals from the roots to the leaves Xylem - tube-likecells that carry food, which is made in the leaves, to all parts of the plant Phloem-

  14. L k Xylem & Phloem: Phloem Take another xylem

  15. Xylem & Phloem

  16. PLANTS Vascular Nonvascular Vascular Plants: Two Main Groups Seedless Plants Seed Plants 1) seedless plants • Vascular plant that DO NOT have seeds Ex: ferns 2) seed plants • Vascular plant that have seeds for reproduction Ex: conifers & flowering plants

  17. Vascular Plants: Seedless (ferns) Ferns- seedless plants • usually grow in moist shady areas typical fern • they have adapted to grow in other environments: -aquatic (water) -dry climates -tropical regions water horn fern tropical fern • stem stores the food & water

  18. Vascular Plants: Seedless (ferns) The Fern Leaf • divided into tiny leaflets that look “feathery” • loses leaves at the end of each growing season • ferns are classified by their leaves The Fern Reproduction • reproduce by spores formed on the underside of the leaf • the cases that hold the spores look like brown and orange spots

  19. Vascular Plants: Seedless (ferns) 4 Parts of a Fern: an underground stem that anchored by the roots rhizoid- anchor the fern roots- Frond- full grown leaves that stand vertically tightly coiled new leaves Fiddlehead-

  20. Vascular Plants: Seedless (ferns) 4 Parts of a Fern: roots- rhizoid- Frond- Fiddlehead-

  21. Vascular Plants: Seed Plants (conifers) a type of seed plant that produces its seeds inside a cone Conifer- 2 main parts : embryo- An organism that contains a new young plant and stored food in its earliest stage of birth seed- A plant embryo that contains a new young plant and stored food surrounded by a protective coat

  22. CONIFERS

  23. Vascular Plants: Seed Plants (conifers) 2 Main Types of Plants a type of conifer that keeps its leaves all year long Evergreens- example: pine, spruce, & fir trees • they lose their leaves like a pet sheds (not all at the same time) • some lose their leaves in the fall only such as: • larch, dawn redwood, & bald cypress

  24. Vascular Plants: Seed Plants (conifers) 5 important facts about conifers 1) ¾ of the worlds lumber is from conifers 2) provide almost all of the worlds paper 3) source of turpentine's, disinfectants, and fuel 4) Provides food for many animals 5) Provides shelter for many animals

  25. Vascular Plants: Seed Plants (conifers) Brainstorm Directions: List 10 items that are made from conifers

  26. Slide Questions Part One (slides 1-10) Directions:Answer the following questions 1) List the 4 general characteristics of plants 2) Define photosynthesis. 3) In which organelle does photosynthesis take place? 4) What are the 3 main ingredients for photosynthesis? 5) List two function (job) of the cell wall in plants. 6) List the two main types of plants.
