26
Q

Eukaryote

A

Any cellular organism that contains a membrane bound nucleus (complex organisms)

27
Q

Unicellular

A

Having or consisting of a single cell

28
Q

How many cells can Protista have?

A

Unicellular or multicellular

29
Q

How many cells do fungi have?

A

Mostly multicellular

30
Q

How many cells do Plantae have?

A

Mostly multicellular

31
Q

How many cells do Animalia have?

A

Multicellular

32
Q

Autotroph

A

An organism able to form nutritional organic substances from inorganic substances like carbon dioxide

33
Q

Heterotroph

A

Gets nutritional requirements from complex organic substances (eating)

34
Q

Are fungi autotrophs or heterotrophs?

A

Heterotrophs

35
Q

Are Plantae autotrophs or heterotrophs?

A

Autotrophs

36
Q

Are Animalia autotrophs or heterotrophs?

A

Heterotrophs

37
Q

What are the 7 properties all living things share?

A

Cellular organization, homeostasis, metabolism, responsiveness, reproduction, heredity, and growth.

38
Q

What is the smallest unit capable of all life functions?

A

A cell

39
Q

What are cells enclosed in?

A

Membranes

40
Q

What is homeostasis?

A

The maintenance of stable internal conditions in spite of external environment changes.

41
Q

What does a metabolism do?

A

Carry out chemical reactions to obtain energy. All energy comes from the sunlight.

42
Q

What is responsiveness?

A

Maintaining a stable internal environment, living organisms also respond to external environments.

43
Q

Define reproduction.

A

The process by which organisms make more of their own kind from one generation to the next.

44
Q

What is heredity?

A

Passes on an organisms traits to their offspring.

45
Q

What is evolution?

A

Change in inherited characteristics over time.

46
Q

Define growth.

A

Getting bigger/matured. All loving organisms grow. As they grow, must organisms change. That is called development.

47
Q

What was Redi’s experiment?

A

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
Q

What year was Redi’s experiment performed?

A

1668

49
Q

Define classification

A

Grouping of different types of organisms based on similarities in structure and evolutionary relationships.

50
Q

What did Carolus Linneaus do?

A

Devised binomial nomenclature

51
Q

Which of the two names comes first?

A

Genus , Species

52
Q

What do you do to a genus name?

A

Capitalize it and underline.

53
Q

Define taxonomy:

A

Science of describing, naming, and classifying organisms

54
Q

The 3 Domain System is based in the following criteria:

A

1) Presence or absence of a nuclear membrane. 2) Unicellular versus multicellular. 3) Type of nutrition -autotrophs and heterotrophs -

55
Q

Characteristics of Archaea:

A

Most primitive and often love in extreme environments (salt, heat, methane loving) unicellular and no nucleus

Protista, fungi, Plantae, Animalia

61
Q

Kingdom Protista Characteristics:

A

Predominately unicellular organisms with plant/animal like characteristics.

62
Q

Examples of Kingdom Protista:

A

Protozoa and all algae.

A

Called Protozoa. Can live in fresh or saltwater, soul, it other bodies of organisms.

66
Q

Plant like Protists:

A

Called algae. Contain chloroplast and are autotrophic.
