Six Kingdoms

Vocabulary Lesson 15

kingdom 1. the highest level of organization

species 2. a group of similar organisms that can breed to produce fertile offspring; the lowest level of classification

prokaryote 3. a unicellular organism whose cell does not contain a nucleus

eukaryotes 4. a living thing whose cells contain a nucleus

autotroph 5. an organism that is able to make their own food

heterotroph 6. an organism that gets its food by eating other organisms

scientific name 7. the name given to an organism based on the genus to which it belongs and its species name

plants 11. all are multicellular, eukaryotic, and autotrophic

bacteria 12. unicellular, prokaryotic

Eubacteria unicellular, prokaryotic the larger of the two kingdoms (meaning there are more of this type)

Archaebacteria unicellular, prokaryotic Often found in extreme conditions

animals 13. all are multicellular, eukaryotic, and heterotrophic

fungi 14. most are multicellular, one kind is unicellular, all are eukaryotic, and heterotrophic

protists 15. divided into 3 groups: plant-like, animal-like, and fungus-like

Three things that all living things need: 1 food 2 water 3 a place to live

What characteristics determine how to classify an organism into a kingdom?

How many cells they are made up of If those cells have a nucleus How they get their nutrition

The five characteristics of living things are that they: 1 Are made of cells 2 Respond to stimuli 3 Use energy 4 Reproduce 5 Grow & develop

How do you know which animals are more closely related to others on a classification tree? The closer the branches are, the more alike the organisms are. The closer to the bottom they are, the longer they have been on Earth. The higher they are, the more complex they are.

Genus and species names Where does the scientific name of a creature come from?

What saying can help you remember the order of the levels in a classification chart? King Phillip Came Over For Good Spaghetti

How do you write the scientific name for an organism? The genus name comes first and is always capitalized The species name comes second and always starts with a lower case letter If typed, use italics; if handwritten, underline it Felis domesticus Felis domesticus Canis familiaris Canis familiaris

virus a parasite that often causes disease and that consists essentially of an inner core of RNA or DNA surrounded by an outer protein coat; they are unable to reproduce without a host cell; not considered living organisms

What are some diseases caused by viruses? HIV / AIDS Chicken Pox Common Cold Pink Eye (Conjunctivitis) Ebola Hepatitis Flu (Influenza) Measles Meningitis Mononucleosis Norwalk Virus Rabies Rotavirus West Nile Small Pox

vaccine What is a possible treatment for a virus?

What conditions do bacteria like most? Most bacteria like a warm, dark, and moist environment.

Where can bacteria be found? everywhere

binary fission the process of one organism dividing into two organisms The one main chromosome makes a copy of itself. Then it divides into two.

endospore a thick walled, protective structure that forms inside a bacterial cell when conditions are unfavorable for survival (like a force field)

What are 3 ways to control bacteria in food? 1) Canning 2) Pasteurization 3) Dehydration

What are some diseases caused by bacteria? Food poisoning (Salmonella or E. coli) Lyme disease Tetanus Tuberculosis strep throat

What is a possible treatment for a bacterial infection? vaccine Antibiotics

antiseptics chemicals that kill bacteria on living things OK to be on your body i.e.: iodine, hydrogen peroxide, alcohol, soap, mouthwash

disinfectants stronger chemicals that destroy bacteria on objects or nonliving things not OK to be on your body i.e.: Lysol, bleach

Bacteria are classified by shape into 3 groups: Spiral Rod-shaped Round http://www.east-buc.k12.ia.us/Ins/00-01/HS/le1.GIF

Archaebacteria Are organisms in this kingdom unicellular or multicellular? Do they have a nucleus? Are they able to make their own food or must they take in food? Where are they found?

Archaebacteria Are organisms in this kingdom unicellular or multicellular? unicellular Do they have a nucleus? prokaryote Are they able to make their own food or must they take in food? autotrophic/heterotrophic Where are they found? They are often found in extreme conditions, such as hot springs.

Eubacteria Are organisms in this kingdom unicellular or multicellular? Do they have a nucleus? Are they able to make their own food or must they take in food? Which is the larger kingdom of bacteria?

Eubacteria Eubacteria are unicellular organisms. They are prokaryotes. Some of them are able to make their own food, while some of them must take in food-- autotrophic/heterotrophic This is the larger of the two bacteria kingdoms.

Protists Are organisms in this kingdom unicellular or multicellular? Do they have a nucleus? Are they able to make their own food or must they take in food? Into what groups are they divided?

Protists Some protists are single-celled organisms and some are made of many cells. All protists have a nucleus. eukaryotes Some of them are able to make their own food, while some of them must take in food. They are divided into three groups-plant-like, animal-like, and fungus-like.

Fungi Are organisms in this kingdom unicellular or multicellular? Do they have a nucleus? Are they able to make their own food or must they take in food? How do they help the Earth?

Fungi Most fungi are made of many cells. All fungi have a nucleus. eukaryotes All fungi must take in food. Fungi are important sources of food and medicines. They help recycle Earth’s wastes. The only unicellular fungi are yeast.

Plants Are organisms in this kingdom unicellular or multicellular? Do they have a nucleus? Are they able to make their own food or must they take in food? Name one important thing plants provide.

Plants All plants are made of many cells. multicellular All plants have a nucleus. eukaryotes All plants make their own food. autotrophs Plants produce food and oxygen, which are required by most organisms on Earth.

Animals Are organisms in this kingdom unicellular or multicellular? Do they have a nucleus? Are they able to make their own food or must they take in food? What do they provide humans with?

Animals All animals are multicellular. All animals have a nucleus. eukaryote All animals must take in food. heterotrophs Animals provide food and companionship in your daily lives.

Vocabulary Lesson 16

classification 8. grouping organisms or objects based on similarities and differences between them

taxonomy 9. the branch of science that deals naming organisms and classifying them into groups

dichotomous key 10. a tool to classify organisms by choosing their characteristics from a series of paired statements

binomial nomenclature a naming system where every organism is given a two-part name (scientific name)

Dichotomous Keys The identification of biological organisms can be greatly simplified using tools such as dichotomous keys. A dichotomous key is an organized set of couplets (paired statements) of characteristics of organisms.

Dichotomous Keys You simply compare the characteristics of an unknown organism against an appropriate dichotomous key. These keys will begin with general characteristics and lead to couplets (paired statements) indicating progressively specific characteristics. If the organism falls into one category, you go to the next indicated couplet. By following the key and making the correct choices, you should be able to identify your specimen to the indicated taxonomic level.
