26
Eukaryote
Any cellular organism that contains a membrane bound nucleus (complex organisms)
27
Unicellular
Having or consisting of a single cell
28
How many cells can Protista have?
Unicellular or multicellular
29

Mostly multicellular
30
How many cells do Plantae have?
Mostly multicellular
31
How many cells do Animalia have?
Multicellular
32
Autotroph
An organism able to form nutritional organic substances from inorganic substances like carbon dioxide
33
Heterotroph
Gets nutritional requirements from complex organic substances (eating)
34
Are fungi autotrophs or heterotrophs?
Heterotrophs
35
Are Plantae autotrophs or heterotrophs?
Autotrophs
36
Are Animalia autotrophs or heterotrophs?
Heterotrophs
37
What are the 7 properties all living things share?
Cellular organization, homeostasis, metabolism, responsiveness, reproduction, heredity, and growth.
38
What is the smallest unit capable of all life functions?
A cell
39
What are cells enclosed in?
Membranes
40
What is homeostasis?
The maintenance of stable internal conditions in spite of external environment changes.
41
What does a metabolism do?
Carry out chemical reactions to obtain energy. All energy comes from the sunlight.
42
What is responsiveness?
Maintaining a stable internal environment, living organisms also respond to external environments.
43
Define reproduction.
The process by which organisms make more of their own kind from one generation to the next.
44
What is heredity?
Passes on an organisms traits to their offspring.
45
What is evolution?
Change in inherited characteristics over time.
46
Define growth.
Getting bigger/matured. All loving organisms grow. As they grow, must organisms change. That is called development.
47
What was Redi's experiment?
He put meat in a jar and covered one, but left the other uncovered. This disproved spontaneous generation because the covered one had no maggots.
48
What year was Redi's experiment performed?
1668
49
Define classification
Grouping of different types of organisms based on similarities in structure and evolutionary relationships.
50
What did Carolus Linneaus do?
Devised binomial nomenclature
51
Which of the two names comes first?
Genus , Species
52
What do you do to a genus name?
Capitalize it and underline.
53
Define taxonomy:
Science of describing, naming, and classifying organisms
54
The 3 Domain System is based in the following criteria:
1) Presence or absence of a nuclear membrane. 2) Unicellular versus multicellular. 3) Type of nutrition -autotrophs and heterotrophs -
55
Characteristics of Archaea:
Most primitive and often love in extreme environments (salt, heat, methane loving) unicellular and no nucleus
56
Characteristics of bacteria:
primitive cell structure, no organized nucleus or nuclear membrane.
57
Coccus shape:
Sphere
58
Bacillus shape:
Tubular
59
Spirrilum shape:
Corkscrew
60
Examples of eukarya:
Protista, fungi, Plantae, Animalia
61
Kingdom Protista Characteristics:
Predominately unicellular organisms with plant/animal like characteristics.
62
Examples of Kingdom Protista:
Protozoa and all algae.
63
Kingdom Protista have true:
True nucleus and nuclear membrane.
64
Most Protista are:
Motile (can move)
65
Animal-like Protists:
Called Protozoa. Can live in fresh or saltwater, soul, it other bodies of organisms.
66
Plant like Protists:
Called algae. Contain chloroplast and are autotrophic.
