What are some features of tracheophytes: vascular plants?
Vascular plants are plants that have a vascular tissue (“pipes”) to transport water and nutrients, therefore they MUST be multicellular since you can’t have such complex structures in a single cell. Most vascular plants are autotrophs (they “make” their own food using sunlight as the source of energy), and some are parasites of other vascular plants. Heterotrophs consume other organisms to get their nutrients (parasites, predators, etc). The major groups of vascular plants are non-seed producing plants, like ferns and lycophytes (clubmosses, etc), and the seed plants, which include the gymnosperms (conifers like pine trees are in this group) and the flowering plants (angiosperms).
