Classification / Taxonomy / Systematics Review
DOMAINS
1. Draw a phylogenetic tree (an evolutionary tree
diagram) illustrating the relationship between
the three domains.
2. In the table below outline the key characteristics that distinguish the three domains. Include examples of organisms in
each domain.

Eukarya
Characteristics
Example
Eukaryotic Kingdoms
In the table below outline the key characteristics that distinguish the four kingdoms of the Domain Eukarya by making
notes on the following: (1) mode of nutrition, (2) presence or absence of cell wall, (3) method(s) of reproduction, and 94)
any other notable characteristic.

Eukaryotes: Plants
In the table below outline the key characteristics that distinguish the four groups of land plants by making notes on the
following: (1) presence or absence of vascular system, (2) dominance of gametophyte vs. sporophyte, (3) mode of
reproduction, and (4) any other notable characteristics.

In the table below outline the key characteristics that distinguish the groups of the Kingdom Animalia by making notes on
the following: (1) common name & examples, (2) type of symmetry, (3) no coelom, pseudocoelom, or coelom, (4) saclike
or tublike gut, (5) soft body, exoskeleton, or endoskeleton, and (6) any other notable characteristic (e.g. proto- vs
deutersotome, etc).

the following: (1) common name and examples, (2) body structure & type of body covering, (3) structure used for gas
exchange, (4) structure of heart, (5) ectotherm vs. endotherm, (6) mode of fertilization, (7) mode of development, (8) any
other notable characteristic.
