  1. Warm Up Friday 4/4/14 1)Which body system helps you fight off viruses such as the flu?

  2. Objectives • I describe common characteristics of plants by completing my 3-5 complete sentence summary.

  3. Intro toKingdom Plantae

  4. Common Characteristics of Kingdom Plantae • Multicellular • Eukaryotic • Cell wall made of cellulose • Photosynthesis ( have chloroplast ) • Autotrophic

  5. Why are plants important? • Provides food to animals and plants. • Produce oxygen • Renew the air • Give us medicines • Provide a home for wildlife • Beautify surroundings • Provides building materials • Give us clothings

  6. Plant Cell Review Endoplasmic Reticulum Vacuole Nucleus Helps synthesize proteins and lipids Brain of the cell Contains genetic info DNA! Storage In plants can take up to 90% of the entire cell Golgi Apparatus Mitochondria Packages and delivers proteins Energy Cellular Respiration ATP Cell Wall Chloroplast Support and structure Composed of cellulose Contains Chlorophyll Site of photosynthesis Ribosomes Cell Membrane Site of protein synthesis Gateway to the cell

  7. 1.Draw a vein diagram and give 3 differences between a plant and an animal cell. • 2.Give 3 similarities between them.

  8. What plants need to live: • Water • Soil ( nutrients ) • Sunlight • Carbon Dioxide

  9. * Remember the plant cell is different that the animal cell. • Cell Wall • Chloroplast • One big vacuole

  10. Plant Cell Support; made of cellulose Storage Site of photosynthesis

  11. Basic Anatomy • The Leaf 1. Blade=where photosynthesis takes place 2. Vein=carries water, minerals, & sugar through blade. 3. Petiole=connects the leaf to the stem; transports fluids Blade Petiole Vein

  12. The leaf cross-section 3 parts: 1.Cuticle= waxy covering; prevents water loss 2. Stomata= allows gas & water vapor in & out ( the opening ) 3. Guard Cell= opens & closes stomata. ( surrounds the stomata ) *Paste picture into notes.

  13. A closer look…. Draw & Label

  14. Transpiration = loss of water through the stomata.

  15. Basic Anatomy B. The Stem 3 types of tissue: • Dermal= outer layer; covers & protects • Ground= storage, support, & photosynthesis. • Vascular = transport water & nutrients a. Xylem b. Phloem

  16. Xylem They are dead cells; they transport water & minerals salts . * Dead xylem makes rings in trees.

  17. Phloem They are living cells; transport “food” ( the sugar produced by plants )

  18. Basic Anatomy 3) The Root • Absorb water & minerals • Anchors plants • Some store food

  19. Roots Root tip= site of maximum absorption of water & mineral salts Root hairs: they increase surface area for absorption.

  20. Root Cap It covers & protects the root as it grows into the Earth.

  21. Root Types • Tap root= single ( main ) root; deep strong anchor for plant; gets ground water. Example: Carrots, beets

  22. Root Types Fibrous root= many primary roots; found in upper soil; cover wide area Examples: Grass, ferns, banana, onion

  23. Can you tell the difference?

  24. Banyan Trees • Common in Hawaii but grow in a very uncommon way: the roots grow in reverse, reaching down to the ground from the branches above.  • Roots are considered "aerial prop roots"

  25. Plant Drawing Activity 1) Draw a picture of a plant. Include: a. blade e. tap root or b. vein fibrous root c. petiole f. root tip d. stem g. root hairs 2) Use at least 2 colors. 3) Worth 25 ponts!

  26. Warm Up Monday 4/7/13 • What is the opening in the guard cell called? • What is its function?

  27. Kingdom Plantae Notes # 2

  28. Objectives • I will compare and contrast monocot and dicot plants by completing my 3-5 complete sentence summary.

  29. Plant Classification Plants are classified by their reproductive systems. • Without seeds- Sporophytes • With seeds- Spermatophytes

  30. Angiosperms • Flowering plants • Bear seeds within ovaries which surround & protect the seed. • Two types: a. Monocot b. Dicot

  31. Monocot & Dicot Monocot = one cotyledon *Latin Root: Mono=one Dicot = two cotyledon *Latin root: Di=two

  32. Monocot • Single cotyledon- seed leaf • Parallel veins • Flower petals in multiples of 3 • Vascular tissue scattered throughout the stem • Fibrous root

  33. Dicots • Two cotyledon leaves • Branched veins • Flower petals in multiples of 4 or 5 • Vascular tissue arranged in a ring • Taproots

  34. Angiosperms life cycles • Annuals = one growing season • Biennials= two growing seasons • Perennial= live many years Morning Glory Japanese boxglove Azaleas

  35. Adaptations in plants Tropism= the growth of a plant to an external stimulus such as 1. light ( phototropism ) 2. touch ( thigmatropism ) 3. gravity ( geotropism ) Greek root TROPE= “ a turning “

  36. Phototropism = Growth towards light

  37. Thigmatropism = growth towards touch or a solid object Venus Fly Trap Twining Vine

  38. Thigmatropism The coiling is caused by the sides of the vine growing at different rates.

  39. Geotropism = Growth towards gravity No matter which way you turn the seed, the root will respond to gravity and grow toward the Earth

  40. Adaptations • Cacti- needle like leaves to prevent water loss & protection

  41. Adaptations • Venus fly trap- trap insects b/c it lives in nutrient depleted soil • Pitcher plant- leaves made to trap insects.

  42. Leaf Cross-Section Activity 1) Draw a cross-section of a leaf 2) Label a. Cuticle b. Guard Cell c. Stomata 3) Use at least 2 colors 4) Worth 4 stamps

  43. Warm Up Tuesday 4/08/14 Explain the two ways plants are classified?

  44. Kingdom Plantae Notes # 3

  45. Objectives • I will identify parts of a flower by filling in the picture of a flower in my notes.

  46. Turgor Pressure video

  47. Turgor Pressure = pressure exerted on the plant’s cell wall by water passing INTO the cell by osmosis. *Hypotonic *Hypertonic

  48. Reproduction of Plants 1) Spores = reproductive organ that requires water to be transported. Example: spores on a fern

  49. Reproduction of Plants 2) Seeds = organ that contains an embryo, food supply, & protective coat. Remember: Cotyledon= stores or absorbs food for the developing embryo.

  50. Reproduction in Plants 3) Fruit = houses the seeds & aids in dispersal by wind, water, insects, & other organisms a. one seed; ex=peach b. several seeds; ex= strawberry c. some are not edible; ex= walnut shell or coconut shell
