1. INTRODUCTION TO PLANT CLASSIFICATION: CLASSIFYING CLASS 1 PLSC 1 Class Unit 2

2. Concept Map! Vocab:

3. Essential Question  How are plants named and classified ?

4. Warm-Up  Take 1 minute to write down as many animals as you can name  Take 1 minute to write down as many plants as you can name  Class Discussion: As we go around the room put a check by names that have already been read.

5. Videos  Intro to Classifying Living Things

6. Objectives  Describe the system used for naming and classifying plants.

7. Nomenclature  Definition : The system of naming things  Goal: To have specific labeling system to help with identification

8. Where did it start?  Aristotle  Classified animals based on similarities into Genera

9. K P C O F G S  Kingdom - King  Phylum - Phillip  Class - Came  Order - Over  Family - For  Genus - Good  Species - Spaghetti  Activity: Each table come up with your own memory sentence ! You have 3 minutes. Write them on the board to share with the class.

10. 5 Kingdoms and Descriptions  Prokaryota  Protista  Fungi  Plantae  Animalia  Most plants that we will be discussing will be in the Kingdom Plantae  Unicellular and colonial  Unicellular protozoans  Haploid and dikaryotic (binucleate) cells, multicellular, generally heterotrophic  Haplo-diploid life cycles, mostly autotrophic  Multicellular animals, without cell walls and without photosynthetic pigment

12. What do you notice?  What do you notice about how animals are grouped together and named?  Are they grouped by similarities or differences?

13. Naming Plants  Plants are labeled by similarities  What do scientists look for? Flowering pattern Stem structures Leaf structures Life cycles Genetic similarities  All plants belong to the Kingdom Plantae

14. Taxonomy  Definition: The science of naming  Each plant is categorized with 7 names  We normally only use the last 2 this is called  Binomial nomenclature A 2 name system of identification

15. Binomial Nomenclature  Developed by Carolus Linnaeus  1707- 1778  Botanist, Physician, Zoologist

16. What does it look like?  Always use the last 2 “names” to label plants  **Keep in mind this is scientific classification!! **  Genus name is always capitalized  Species name is always lower case  Example: Liriodendron tulipifera

17. Latin Example: Phytolacca americana  Phytolacca: Plant with red milk, sap  Americana: Of the Americas  Common Name: Pokeweed, Red Ink Plant

18. Naming Continued…  Genus is a group of plants with similar characteristics  Species are plants that can mate together freely in the wild  Common names are used to help non-scientists classify and remember plants

19. Common Name: Yellow Tulip Poplar Scientific Name: Liriodendron tulipifera

20. Class Activity: Practice with Nomenclature  Use the internet to ID 10 plants.  8 plants should have the Scientific Name, and Common Name  2 plants should have the entire K F C O F G S and Common Name  The plants must be found in Delaware/North Eastern US

21. Class Activity-Library Wed 1:30-2:30  PlantUnit2Wrksht1  Complete the worksheet provided. Use COMPLETE sentences and CORRECT punctuation.  Write legibly (so others can read what you write!)

22. Closing  Word Wall:  Taxonomy, Binomial Nomenclature  Exit Question  Into what types of groups are plants classified?  Next Class  Explore major plant groups

23. INTRODUCTION TO PLANT CLASSIFICATION: CLASSIFYING PLANTS 2 PLSC 1 Class Unit 2

24. Warm Up Can you name any of these?

25. Life Science Plants Video

26. Essential Question  What are some ways that we can group plants together?

27. Objectives  Identify the major groups of plants

28. Bryophytes  Classified in the Phylum Bryophyta  Non Vascular  No conducting tissue  Examples  Mosses and liverworts  Where do you find them?  They live in damp places  All other plants are in the Phylum Tracheophyta

29. Bryophyte

30. Ferns  Reproduce by spores  Dependent on water to for their sperm to swim during reproduction  No true leaves!  Fronds have a double purpose Food production ( photosynthesis) Spore formation  Fronds unfold from the center of the plant. New fronds are called fiddleheads

31. Fern

32. Gymnosperm  Plants that reproduce with “naked” seeds on scales  Use CONES to reproduce  Called a Conifer They do not drop their leaves  Leaves are modified into needles

33. Gymnosperm

34. Coniferous vs. Deciduous  Coniferous: Do not drop their “leaves”/needles in winter  Deciduous: Drop their leaves in winter. Leaves change color

35. Angiosperms  Seeds develop in a fruiting body  All angiosperms reproduce with flowers  Two Types

36. Monocots and Dicots  Monocots: single cotyledon, flower parts in multiple of 3’s, parallel veins  Dicots: 2 cotyledons, flower parts in multiples of 4 or 5, netted veins, stems in a ring pattern

37. Make a VEN diagram (Separate sheet of paper)

38. Scavenger Hunt!  Find the most common monocot on school grounds  Find the most common dicot on school grounds  Find a plant with a “naked seed”  Find a fruiting body  Find an angiosperm  Find a gymnosperm  Find a coniferous leaf  Find 3 deciduous leaves  You have from 8:35-8:55 Back in the classroom by 9am

39. Outside Activity  Each student will have clippers.  Each student will collect 4 specimens outside  Each student will make rubbings of 3 plants  Each student will identify the all plant specimens as monocot or dicot  You will be responsible for explaining your answers.

40. INTRODUCTION TO PLANT CLASSIFICATION: CLASSIFYING PLANTS 3 PLSC 1 Class Unit 2

41. WARM UP  Divide your plants into the groups discussed last class. Separate them by table. Use your notes to help you.  Separate them into Monocots, Dicots, Conifers, and other groups we talked about yesterday in class. Only use four.  Be prepared to support you answer!!

42. Essential Question  What is the difference between biennial, perennial, and annual plant life cycles?

43. Warm Up  Name any annual, biennial, and perennial plants that you know

45. Annual Plant Life Cycle  Plants which grow from a seed, then flower, then produce seeds in one season.  After flowering the plant will DIE  It only lives for 1 season  Normally herbaceous  No woody stem

46. Biennial Life Cycle  Plants which live for two years, then flower and die.  Only flower in second season of life  Examples: Carrots, Foxgloves, Queen Anne’s Lace

47. Perennial Life Cycle  Plants which live for three or more years.  Often flower for a short time every year  Hold some energy for reserves for next season  Herbaceous and Woody stems

48. Herbaceous

53. INTRODUCTION TO PLANT CLASSIFICATION: PARTS OF PLANTS-> ROOTS PLSC 1 Class Unit 2

54. Essential Question  What are the functions of a plant’s roots?

55. Warm-Up  Which one is not a root?

56. Plant Health  Relies on the ROOTS  Constantly growing to remain healthy  That’s why plant’s need space in their pot!  Without space plants become root bound

57. Root bound plant

58. On your Table  Answer the following question about your plant  Is it root bound?  If YES How do you know? What does it look like?  If NO How do you know? What does it look like?

59. Roots: What’s the job?  A. The roots must absorb all of the water and minerals that a plant needs to live.  B. The root must anchor the plant to the ground and support the above ground part of the plant.  C. The roots store food that has been made through photosynthesis.  This food can be used later when a plant needs it to grow or survive.

60. Root Anatomy ROOT: Absorbs nutrients, minerals, and salts. Stores food. Passage of nutrients PRIMARY ROOT: Anchors plant. Known as tap root SECONDARY ROOT: Collects and transports nutrients up and down ROOT CAP: Protect the root as it pushes through the soil. Protects the apical meristem from damage.

61. Root Anatomy: A closer look

62. Roots  When seeds germinate, roots are the first to emerge.  Roots are covered with cells  Called the epidermis Increased surface area= increased food  Epidermis cells grow long and form root hairs

63. Roots: Two Types  Tap Root System: Primary roots and secondary roots  Fibrous / Adventurous Root System: Primary root grows, then dies. Multiple roots take its place

64. Healthy Roots Unhealthy Roots  Fresh smell, white in color, grow throughout pot

68. INTRODUCTION TO PLANT CLASSIFICATION: PARTS OF PLANTS-> STEMS PLSC 1 Class Unit 2

69. Essential Question  What are the functions of the stem?

70. Warm Up  Do you recognize these stems?

71. Stems : What’s the Job?  Support the leaves in correct position to collect sunlight  Move water, minerals, and manufactured food through plant  Green stems practice photosynthesis and produce food  Store food

72. Stem: External Anatomy  Apical/Terminal Bud- growth occurs from here. Adds length to the plant

73. Stem: External Anatomy  Node: Where the leaf attaches to the stem  Internode: The area between leaves  Lateral Bud: Located next to the leaf attachment to stem

74. Stem: External Anatomy  Bud Scale: Protects developing bud  Leaf Scar: Left behind by fallen leaves
