LAB 6 Four major types of plants Angiosperm - MAGNOLIA→ fruits and seeds. Bryophytes- MOSS→ don’t have tissue (xylem nor phloem), neither seeds. ’’ Non- vascular plants’’. Instead, they have rhizoids. Gymnosperms- PINE→ have needles and cones; have seeds but no flowers neither fruits Pteridophytes – FERN → have vascular tissue but no seeds. ‘’seedless vascular plants’’ Vascular tissue is important to transport nutrients and water through the plant --Female structures--/Carpel Stigma: sticky part, receives the pollen grains Ovule: develops into a seed, egg cells Ovary: develops into a fruit --Masculine structures— /Stamen Anther: Produces polen Filament: supports the anther Phylogeny: study of evolutionary relationship between organisms Cladograms: tree-like diagrams that show relative relationship between organisms Taxonomy are reflection of evolutionary history because they are grouped according to its similarities. This similarity means that both species inherited traits from the same common ancestor. Review cladograms: more simple(ancestor), more recently evolved, new characteristic appear. (solo miralo nuevamente) Ancestral: an organism or particular characteristic of an orga...
