What traits do scientists use to classify living things ?
A. cell structure
B .locomotion
Why would it have been hard for Von Linne to classify Euglena?
Euglena has both characteristics of plants and animals
List 5 kingdoms
1.plants
2.animals
3.protists
4.bacteria
5.fungus
What features do animals cells have that are important in classification?
nucleus that has DNA
What cell parts do animals lack?
1.No cell walls
2. No chloroplast
When classifying an animal what is the first thing a scientist considers?
backbone or no backbone
How do scientists further classify animals with backbones?
1.Body coverings
2.Resporation
3.Reprodution
How do scientists further classify animals with no backbones?
- whether they have a skeleton
2.what the skeleton is made of
3.whether skeleton is internal or external
Why do you think that fungi used to be classified as plants?
Unable to compare cell structure *fungi have no chloroplast
list 2 examples of protists that were disscussed in class?
1.ameoba
2.paramciem
How a protists classified?
1.plant-like
2.animal-like
3.fungis-like
how do bacteria differ from organisms in all other kingdoms?
NO NUCLEUS!!!
How is classification of living things like a library?
subcategories (spices)
categories (genus)
What are some levels of classification?
A. Which is the highest level?
kingdom
B. 2 lowest levels?
genus & species
what does an organisms scientific name tell about it?
genus & species
To identify an organism, what tools could you use?
1.Linnaen system of classification
2.dichonimous key
3. Field guides
What is the scientific name for a Protista?
junk drawer
Explain how the amoeba moves
creeping or pseudopodium
Why can’t the paramecium change shape like the amoeba?
thick outer membrane=pellicle
How does a Euglena move?
used a fiagella
Explain the difference between autotrophic and heterotrophic?
auototrphocic= makes own food
heterotrophic=consumes other organisms’
Bilaterally symmetrical organisms have how many lines of symmetry?
1
Radially symmetrical organisms have how many lines of symmetry?
lines of symmetry are chosen by the centeral point
Asymmetrical symmetrical organisms have how many lines of symmetry?
1 dividing left and right sides
list 4 major charectoristics that all animals share
1.eukaryotio
2.mullticellular organisms
3.speacilized tissue
4. made up of cells woth no cell wall
list common charectoristics of a protists
1.nuclear membrane around DNA
2.sexual reproduction
3. asexual reproduction
describe some animal adaptations for escaping a predator?
1.play dead
2. bright color
3. senses
