Vocabulary
What is an autotroph?
An organism that is able to create its own food through capturing energy from sunlight or chemicals.
What are the 3 domains?
Archaea/archaeabacteria, eukarya, and bacteria/eubacteria.
Archaea, bacteria, plantae, animalia, fungi, and fungi.
Name all of the classification levels.
Domain, kingdom, phylum, class, order, family, genus, and species.
What is a dichotomous key?
A set of questions that ask if the unknown organism is or isn't something. You keep answering these questions until it tells you what the organism is.
What is most basic level of organization?
Domain
What are the characteristics of eukarya?
Unicellular and multi-cellular, eukaryotic, have a nucleus, organelles, and are usually bigger.
What makes fungi different from plants? Explain.
Fungi are heterotrophic because they have to "eat" energy from other organisms instead of making energy from the sun or chemicals.
What is the most specific level?
DAILY DOUBLE - Can add up to 400 more!
Species
How do you use a dichotomous key?
First, you read all of the characteristics of your organism. Then, you read the first question, answer whichever option describes your organism, and follow the instructions. You keep doing this until you find your organism.
The taxonomic category that names a group of similar organisms; the 2nd most specific level of classification.
What is the genus?
What are the characteristics of bacteria?
They are mostly unicellular, but some multi-cellular and are prokaryotic. They are on your skin, mouth, and stomach and can actually help humans. They have no nucleus or organelles.
Describe Fungi
Has a cell wall, heterotrophic, mostly multi-cellular, some uni-cellular, eukaryotic.
Classify the tiger's domain and kingdom
Can all organisms be found in a dichotomous key? Explain.
DAILY DOUBLE - Can add up to an extra 600!
No, they cannot because a dichotomous key can lead one to a question and the question doesn't apply to the unknown organism at all.
What is homeostasis?
DAILY DOUBLE - Can add up to an extra 800 to the normal amount!
The process of maintaining a stable internal environment even when external conditions change.
They are not very similar. Domains are very diverse.
What makes protists different from the rest of the eukarya?
They are usually uni-cellular, though some are multi-cellular. They are less complex and are all of the organisms that aren't fungi, animals, or plants.
Why is classification important?
Classification is important because it allows scientists to create organism's evolutionary data, find connections between organisms, and it is organized.
Organism to be found: Does have a nucleus, has fur
1. Domain? Eukarya - Go to 2 Bacteria - Go to 3
2. Has a beak? Yes - Go to 4 No - Go to 5
3. Harmful to humans? Yes - C. Diff No - Rhizobacteria
4. Legs longer than 4 feet? Yes - Sandhill Crane No - Hummingbird
5. Has fur? Yes - House cat No - Go to 6
6. Has gills? Yes - Go to 7 No - Frog
7. More than 5 teeth? Yes - Lemon Shark No - Bluegill
House cat
What is Archaea and what is the other name for it?
Archaea is an extremely diverse domain and kingdom of prokaryotes that are "extremophiles" that thrive in extreme environments. Archaeabactera
What are the characteristics for Archaea?
DAILY DOUBLE - Can add up to an extra 1000!
Hot, salty, or acidic environments; usually underwater with low oxygen levels. They are extremophiles and unicellular. Prokaryotic.
What is the most complex kingdom? (As in amount of cells, the organism's structure, parts of the organism)
DAILY DOUBLE - Can add up to 1000 more!
Animalia
Who was Carl Linnaeus and why was he important?
Carl Linnaeus was a scientist who created the base of the modern day classification system. He also invented the binomial nomenclature system.
