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.

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
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.
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
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 nomenclature
A 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 non-scientists 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
PlantUnit2Wrksht1 Complete the worksheet provided. Use
COMPLETE sentences and CORRECT punctuation.
Write legibly (so others can read what you write!)
Closing
Word Wall: Taxonomy, Binomial Nomenclature
Exit Question 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 and liverworts Where do you find them?
They 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 unfold from the center of the plant . New 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
9am
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
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
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
