Describe an Archaea bacteria.

bacteria found in hot, acidic environments

What is a main difference between prokaryotes and eukaryotes?

Eukaryotes only have membrane bound organelles

What type of information would we find on a dichotomous key?

logical, efficient traits that are easily observed

What is the purpose of a dichotomous key?

to identify species using specific traits

What is true about a phylogenetic tree?

links taxa to a common ancestor

6
What type of information would we find on a dichotomous key?
anatomical structures that could lead one to link species
very specific characteristics to very broad characteristics
logical, efficient traits that are easily observed
genetic information for the species
7
What is the purpose of a dichotomous key?
to identify traits that are passed down generations
to see how organisms are related to their ancestors
to make a cladogram
to identify species using specific traits
8
What is true about a phylogenetic tree?
links taxa to a common ancestor
no chronological order, just linked
hypothesis to what is supported by evidence
everything is exact in description and representation
9
Use the dichotomous key to identify the organism labeled 3

bacteria
dogs
algae
oak tree
11
Why did we switch to a three domain system instead of the two kingdom system?
early systems used biochemical analysis
modern systems used biochemical analysis
organisms have become more complex
scientists wanted to keep the system simple

wolf
dog
13
What description would best be used to characterize plants?
what type of vascular tissue
use of cellular respiration
presence of cell walls
production of oxygen
14
If I was comparing 2 diff. animal cells, what could I look at in the cell to tell them apart?
nutritional requirements of the organism
number of cells in organism
internal organization of the cell
chemical composition of cell membrane
15
What is the first step in making a dichotomous key?
use the internet to do research on the species
going outside and finding the species in the natural place
making a list of characteristics that the species has
find fossil information on the species
16
Why did they split up the bacteria kingdom into two separate kingdoms?
bacteria are closely related to other bacteria
bacteria are not related to each other or other kingdoms
some bacteria are helpful and harmful to us
some bacteria are more closely related to animals
