The dominant plants of the Earth, encompassing more than
250,000 species.
Encompass approximately 750 species
Occupy both land and water.
Are land dwelling only.
Of more recent evolutionary origin. . Of more ancient origin.
Encompass both woody and herbaceous
Encompass only woody forms.
Leaves are mostly broad and flat. Leaves are mostly needle-like
Have flowers. Have strobili or cones.
Lack archegonia in embryo sac. Archegonia are present.
Possess mostly fibrous roots Taproots predominate.
Have both tracheids and vesseilns the xylem. Have tracheids only.
Exhibit deliquescent branching. Exhibit excurrent branching.

Many species have both microsporangia and megasporangia in
the same flower.

Microsporangia and megasporangia are always separate.
Divided into monocots and dicots. Polycotyledonous.
