Essential Question How are plants named and classified ?

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.

Videos Intro to Classifying Living Things

Objectives Describe the system used for naming and classifying plants.

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

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

KPCOFGS 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.

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

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

Naming 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

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

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

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

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

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 nonscientists classify and remember plants

Common Name: Yellow Tulip Poplar Scientific Name: Liriodendron tulipifera

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

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

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

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

Warm Up Can you name any of these?

Life Science Plants Video

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

Objectives Identify the major groups of plants

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

Bryophyte

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 New unfold from the center of the plant. fronds are called fiddleheads

Fern

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

Gymnosperm

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

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

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

Make a VEN diagram (Separate sheet of paper)

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 9 am

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.

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

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!!

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

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

SENIORS ONLY! BE DONE BY THE END OF ANNOUCEMENTS Get out a sheet of paper and nominate 1 boy and. W 1 girl for each of the Give to Ms. 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

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

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

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

Herbaceous

Woody

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

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

Warm-Up Which one is not a root?

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

Root bound plant

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?

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.

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.

Root Anatomy: A closer look

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

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

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

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

Essential Question What are the functions of the stem?

Warm Up Do you recognize these stems?

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

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

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

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

Stem: External Anatomy Lenticels: Openings on bark where gases are exchanged

Activities: Outside: External Stem Anatomy Search Use vocabulary from class and identify vocabulary in the outside forest.
