Objectives
Describe the system used for naming and classifying plants.
![Page 7: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/7.jpg)
Nomenclature
Definition : The system of naming things
Goal: To have specific labeling system to help with identification
![Page 8: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/8.jpg)
Where did it start?
Aristotle Classified animals
based on similarities into Genera
![Page 9: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/9.jpg)

Activity: Each table come up with your own memory sentence ! You have 3 minutes. Write them on the board to share with the class.
![Page 10: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/10.jpg)
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
![Page 11: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/11.jpg)
![Page 12: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/12.jpg)
What do you notice?
What do you notice about how animals are grouped together and named? Are they grouped by similarities or
differences?
![Page 13: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/13.jpg)
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
![Page 14: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/14.jpg)
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
![Page 15: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/15.jpg)
Binomial Nomenclature
Developed by Carolus Linnaeus
1707- 1778 Botanist,
Physician, Zoologist
![Page 16: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/16.jpg)
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
![Page 17: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/17.jpg)
Latin Example: Phytolacca americana
Phytolacca: Plant with red milk, sap
Americana: Of the Americas
Common Name: Pokeweed, Red Ink Plant
![Page 18: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/18.jpg)
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
![Page 19: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/19.jpg)
Common Name: Yellow Tulip Poplar
Scientific Name: Liriodendron tulipifera
![Page 20: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/20.jpg)
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

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
![Page 29: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/29.jpg)

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
![Page 31: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/31.jpg)

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
![Page 33: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/33.jpg)

Coniferous vs. Deciduous
Coniferous: Do not drop their “leaves”/needles in winter
Deciduous: Drop their leaves in winter. Leaves change color
![Page 35: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/35.jpg)

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
![Page 46: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/46.jpg)
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
![Page 47: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/47.jpg)
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
![Page 48: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/48.jpg)

INTRODUCTION TO PLANT CLASSIFICATION:PARTS OF PLANTS-> ROOTS
PLSC 1 Class Unit 2
![Page 54: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/54.jpg)
Essential Question
What are the functions of a plant’s roots?
![Page 55: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/55.jpg)
Warm-Up
Which one is not a root?
![Page 56: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/56.jpg)
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
![Page 57: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/57.jpg)
Root bound plant
![Page 58: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/58.jpg)
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?
![Page 59: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/59.jpg)
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.
![Page 60: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/60.jpg)
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.
![Page 61: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/61.jpg)
Root Anatomy: A closer look
![Page 62: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/62.jpg)
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
![Page 63: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/63.jpg)
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
![Page 64: Introduction to Plant Classification: Classifying Class 1](https://reader035.vdocuments.net/reader035/viewer/2022062304/56814660550346895db38301/html5/thumbnails/64.jpg)
