List four groups of land plants, and able to mark their traits on a phylogeny. - ANSWER 1. nonvascular (mosses) : diverged from green algae 2. seedless vascular (ferns) : adaptive radiations in Devonian & Carboniferous 3. seed plants : recent adaptive radiation, dominate planet! -gymnofers (pine cones) : conifers -angiosperms : flowering plants (DOMINANT) Explain why branching in plants is important. - ANSWER -more reproductive potential, more flowers on a branched tree -more photosynt...

The ecology of algae in aquatic ecosystems parallels that of plants in terrestrial ecosystems. Make three points to support this statement. - Aglae and mosses/plants have similar features such as: - branched apical growth - cuticles - asymmetrical flagellated cells - cellulose, thylakoids, chlorophyll b, some have 2 flagella...
