PART II
TAXONOMY
DIVISION I.—THALLOPHYTA
Plants consisting of a thallus, a body undifferentiated into root,
stem or leaf. The group nearest to the beginning of the plant kingdom
presenting forms showing rudimentary structures which are modified
through division of labor, differentiation, etc., in higher groups.
SUBDIVISION I.—MYXOMYCETES, OR SLIME MOLDS
Terrestrial or aquatic organisms, frequently classified as belonging
to the animal kingdom and found commonly on decaying wood, leaves,
or humous soil in forests. Their vegetative body consists of a naked
mass of protoplasm called the Plasmodium which has a creeping and
rolling motion, putting out and retracting regions of its body called
pseudopodia.
SUBDIVISION II.—SCHIZOPHYTA
This group comprises the "fission plants" whose members possess
a common method of asexual reproduction whereby the cell cleaves or
splits into two parts, each of which then becomes a separate and
independent organism.
I. Cyanophyce^
Plants which are sometimes termed blue-green algae. They contain
chlorophyll, a green pigment and phycocyanin, a blue pigment, a combination
giving a blue-green aspect to the plants of this group. Found
everywhere in fresh and salt water and also on damp logs, rocks, bark
of trees, stone walls, etc. Ex.: Oscillatoria, Gloeocapsa, and Nostoc.
2. SCHIZOMYCETES—BACTERIA
Bacteria are minute, unicellular vegetable organisms destitute of
chlorophyll. They serve as agents of decay and fermentation and are
