Plant Phylogeny?!?

Like animals, plants have a phylogeny tree to indicate new adaptations and advancements in structure as well as function. The ancestors of all plants is the "green plants" which are closely related to the bryophytes, or green algae. The first land plants include nonvascular plants which means that the plants do not have vascular tissue; thus, cannot retain water and deliver it to the rest of the plant. Next is the introduction of the vascular plants. The first vascular plants are the seedless vascular plants. These plants do have vascular tissues, which means that water is vital for their survival. Seedless vascular plants, or pteridophytes, typically favor moist environments and they reproduce by using spores. Seed plants are the most advanced plant species and there are two kinds - gymnosperms (conifers) and angiosperms (flowering).
