Question

Construct (draw) a phylogeny of all plants and include important evolutionary innovations in the nodes of this tree. Create a key (i.e., a list of characteristics) of each of the groups that include the non-vascular plants, vascular plants without seeds, vascular plants with seeds without flowers and flowering plants. You should include the names of the most important groups on each branch (e.g., mosses, ginkgo, ferns, etc.)

Answer 1

Algae: Thallophytic non-embryophytic non-vascular cryptogams
Divided into several subclasses such as Chlorophyceae, Phaeophyceae, and Rhodophyceae

Bryophytes: Embryophytic, nonvascular, archegoniate cryptogams
Three classes: Hepaticopsida, Anthoceratopsida, and Bryopsida

Pteridophytes: Embryophytic, vascular, archegoniate cryptogams
Four classes: Psilopsida, Lycopsida, Pteropsida, and Shenopsida

Gymnosperms: Embryophytic, vascular, archegoniate phanerogams
Three classes: Cycadopsida, Conferopsida, and Gnetopsida

Angiosperms: Embryophytic, vascular, fruit-bearing phanerogams
Divided into monocots and dicots.
