The Kingdom Plantae, defined by enclopedia Britannica, as “multicellular eukaryotic life forms
characterized by […] photosynthetic nutrition, […] essentially unlimited growth at localized
regions, cells that contain cellulose in their walls […] the absence of organs of locomotion, […]
the absence of nervous systems, and life histories that show an alteration of haploid and diploid
generations.” Based on this information, the marine biologist and I would have to observe the
vascular characteristics to correctly identify the taxon (phylum) associated with the plant in
Kingdom Plantae. There are three nonvascular phylum’s which are further classified based on
their if they are mosses, liverworts or hornworts. If the plant was non-vascular we would notice
that the plant’s gametophytes are green, and is attached to the sporophyte of the plant.
Additionally, we would notice that additionally external water is needed for the plant to fertilize,
meaning the plant likely thrives in conditions near large bodies of the water.
On the other side of the phylum taxonomy, there is nine vascular plants, which are then further
divided into seeded and seedless plants.
Three nonvascular (without water conducting vessels) (no roots, small plant lack of vacular
system, found in moist environments, close to water source, )
P. Bryophyta - mosses
P. Hepaticophyta - liverworts
P. Anthocerophyta - hornworts
Nine vascular
Two seedless
P. Pterophyta - ferns, whisk ferns, horsetails
P. Lycophyta - club mosses
Five seeded
P. Coniferophyta - conifers
P. Cycadophyta - cycads
P. Gnetophyta - gnetophyta
P. Ginkophyta - ginkgo
P. Anthophyta - flowering plants - angiosperms
If the plant has lack vessels for conducting water, then we would like observe that
and foodstuffs throughout plant
Gametophytes green, nutritionally independent of, and more
conspicuous than sporophyte
