  1. Introduction to Plant Classification: Classifying Class 1 PLSC 1 Class Unit 2

  2. Concept Map! Unit Name:Intro to Plant Classification Unit EQ: Why are plants classified? Vocab: EQs: 1. How are plants named and classified?

  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

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

  12. 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

  13. 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

  14. Binomial Nomenclature • Developed by Carolus Linnaeus • 1707- 1778 • Botanist, Physician, Zoologist

  15. 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

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

  17. 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

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

  19. 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

  20. 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!)

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

  22. Introduction to Plant Classification: Classifying plants 2 PLSC 1 Class Unit 2

  23. Warm Up Can you name any of these?

  24. Life Science Plants Video

  25. Essential Question • What are some ways that we can group plants together?

  26. Objectives • Identify the major groups of plants

  27. 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

  28. Bryophyte

  29. 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

  30. Fern

  31. 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

  32. Gymnosperm

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

  34. Angiosperms • Seeds develop in a fruiting body • All angiosperms reproduce with flowers • Two Types

  35. 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

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

  37. 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

  38. 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.

  39. Introduction to Plant Classification: Classifying plants 3 PLSC 1 Class Unit 2

  40. 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!!

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

  42. Warm Up • Name any annual , biennial , and perennial plants that you know

  43. SENIORS ONLY! BE DONE BY THE END OF ANNOUCEMENTS Give to Ms. W • Get out a sheet of paper and nominate 1 boy and 1 girl for each of the following: • Best Car • Worst Car • Best Dressed • Best Eyes • Best Instrumentalist • Best Looking • Best Smile • Class Clown • Most Athletic • Most likely to be: • A Celebrity • On Facebook • Stay Friends • Work at AHS • Most school spirited • Most Unique style

  44. 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

  45. 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

  46. 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

  47. Herbaceous

  48. Woody

  49. Video : Review • United Streaming • Life Science: How plants grow • Worksheet with questions. Please answer them. They are due at the end of class.
