|
unicellular
prokaryotic some autotrophic/some heterotrophic cell wall present (peptiodoglycan or cellulose) |
|
Protista - general characteristics
|
unicellular
eukaryotic some autotrophic/some heterotrophic no cell wall |
|
Fungi - general characteristics
|
mostly multicellular
eukaryotic heterotrophic (absorption; external digestive enzymes) no cell wall usually present (chitin) |
|
Plantae - general characteristics
|
Unicellular (algae) or multicellular
eukaryotic mostly autotrophic (photosynthetic) cell wall present (usually cellulose) |
|
Animalia - general characteristics
|
multicellular
eukaryotic heterotrophic (mostly ingestion) no cell wall |
|
Eukaryotic
|
nuclear material (chromosomes) surrounded by a nuclear membrane; nucleus present.
|
|
Prokaryotic
|
nuclear material (chromosomes) not surrounded by a nuclear membrane; nucleus absent
|
|
Autotrophic
|
organisms that can synthesize organic molecules from inorganic materials, usually through photosynthesis
|
|
Heterotrophic
|
organisms that derive energy and organic molecules from other living or dead organisms
|
|
Bilateral symmetry
|
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
|
|
Radial symmetry
|
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
|
|
cellulose
|
carbohydrate; principal component of the cell wall of plants and most eukaryotic algae
|
|
Chitin
|
carbohydrate similar to cellulose, but contains nitrogen; principal component of cell walls in fungi and exoskeletons (not cell walls) of arthropods
|
|
Peptidoglycan
|
carbohydrate; principal component of the cell wall of bacteria
|
|
Vascular tissue
|
in plants, cellular "tubes" that carry water and dissolved substances through the plant; consists of xylem and phloem
