classification including plants
TRANSCRIPT
CLASSIFICATION
with Holt and UnitedStreaming
Classification
Classification is: the grouping of organisms by similar characteristics
Taxonomy: the science of classification
We use a Dichotomous Key which consists of several pairs of descriptive statements where only one will apply to the unknown organism
Who did it and how?
Carl Linnaeus (1700): this scientist classified things by form and structure
He gave organisms a genus and species name (binomial nomenclature)
Latin: the language commonly used for classification
Because it does not change and can be used worldwide
What order is that?
Binomial Nomenclature examined Species: a group of organisms that can
produce viable offspring (viable means it can have its own offspring)
Genus: a group of different species that are similar
Felis catus (household cat)
Binomial Nomenclature
Six kingdoms
• Two prokaryotic kingdoms:1. Archaebacteria2. Eubacteria
• Four Eukaryotic kingdoms:1. Protist2. Plantae3. Fungi4. Animalia
Kingdoms, in depth
Both are Unicellular with No Nucleus (Prokaryotes)
Archaebacteria can live where most organisms could not survive (deep ocean vents, hot spring)
Eubacteria make up most of the other kinds of bacteria on earth.
Example: E. coli, Hot springs algae
Archeabacteria & Eubateria
Protists
A. Unicellular (one celled) and multi-cellular eukaryotic
B. have a nucleusC. autotrophs and
heterotrophs
Example: euglena, paramecium, slime molds
Fungi
A. unicellular and multicellular
B. Heterotroph (obtains energy from other source)
Example: mushrooms, yeasts, molds
Animals
A. multicellular but no cell wallB. heterotrophs- does not make own foodC. have tissues, organs, organ systemsD. Most move
Plants
A. multicellular or unicellular eukaryotic with a cell wall
B. have a nucleusC. autotrophs- makes own
food (photosynthesis)
Example: sequoia, flowers
Do you know plants?
The Plant Kingdom: A quick overview
Plants Plants are
multicellular Plants make their
own food (autotrophs)
There are lots of examples!
2 main groups Plants are either
vascular or nonvascular
Vascular tissue is like tubes that carry water through the plant
Nonvascular plants Have no pipes to
transport water They rely on
diffusion and osmosis
Have no true stems, roots or leaves
They are small
nonvascular Examples are
mosses and liverworts
Vascular plants Have tissues or
pipes to transport water
Have stems, roots and leaves
2 categories There are 2 types
of vascular plants, those that have seeds and those that have no seeds
Seedless vascular plants Examples are ferns,
club mosses and horsetails.
Vascular plant with seeds The vascular plants
with seeds are divided into 2 categories:
Nonflowering
Flowering
Nonflowering seeded plants
Called gymnosperms
Examples are conifers (trees that produce cones) and ginko trees
Flowering seeded plants Called
angiosperms Examples are corn,
tulips, water lillies, peach trees, magnolia trees, grass, palm trees, cactus, cotton plants and much more!
Angiosperms
How can I learn more? More information on all of these plants
can be found in your book in Chapter 12, pages 270-283.
Now, let’s see what you remember…
What are the 2 main groups of plants?
Answer:Vascular and Nonvascular
Which of these two groups includes plants that are large and have pipes to carry water?
Answer: Vascular
Is a moss vascular or nonvascular?
Answer: Mosses are nonvascular
What are the 2 main
groups of vascular plants?
Answer: gymnosperms and angiosperms
Are pine trees gymnosperms or angiosperms?
G: nonflowering
A: flowering
Answer: Pine trees are gymnosperms.
Which one is not an angiosperm?
Water lily
Tomato plant
Cactus
Fern
Palm tree
Corn
Tulip
Answer: Only the fern is seedless and nonflowering.
Plants: We can’t survive without them!
