Biology Diversity Of Life

Front 1

Eubacteria - general characteristics

Back 1

unicellular
prokaryotic
some autotrophic/some heterotrophic
cell wall present (peptiodoglycan or cellulose)

Front 2

Protista - general characteristics

Back 2

unicellular
eukaryotic
some autotrophic/some heterotrophic
no cell wall

Front 3

Fungi - general characteristics

Back 3

mostly multicellular
eukaryotic
heterotrophic (absorption; external digestive enzymes)
no cell wall usually present (chitin)

Front 4

Plantae - general characteristics

Back 4

Unicellular (algae) or multicellular
eukaryotic
mostly autotrophic (photosynthetic)
cell wall present (usually cellulose)

Front 5

Animalia - general characteristics

Back 5

multicellular
eukaryotic
heterotrophic (mostly ingestion)
no cell wall

Front 6

Eukaryotic

Back 6

nuclear material (chromosomes) surrounded by a nuclear membrane; nucleus present.

Front 7

Prokaryotic

Back 7

nuclear material (chromosomes) not surrounded by a nuclear membrane; nucleus absent

Front 8

Autotrophic

Back 8

organisms that can synthesize organic molecules from inorganic materials, usually through photosynthesis

Front 9

Heterotrophic

Back 9

organisms that derive energy and organic molecules from other living or dead organisms

Front 10

Bilateral symmetry

Back 10

body structure with a "head" and a "tail" in which only one sectional plane from the anterior to posterior ends of the animal divides the animal into equal halves

Front 11

Radial symmetry

Back 11

animal body structure in which any section through the mouth and down the length of the body divides the animal into identical halves; generally a circular outline

Front 12

cellulose

Back 12

carbohydrate; principal component of the cell wall of plants and most eukaryotic algae

Front 13

Chitin

Back 13

carbohydrate similar to cellulose, but contains nitrogen; principal component of cell walls in fungi and exoskeletons (not cell walls) of arthropods

Front 14

Peptidoglycan

Back 14

carbohydrate; principal component of the cell wall of bacteria

Front 15

Vascular tissue

Back 15

in plants, cellular "tubes" that carry water and dissolved substances through the plant; consists of xylem and phloem
