EVOLUTION CONNECTION
DRAW IT Draw a phylogenetic tree that represents our current understanding of evolutionary relationships between a moss, a gymnosperm, a lycophyte, and a fern. Use a charophyte alga as the outgroup. (See Figure 26.5 to review phylogenetic trees.) Label each branch point of the phylogeny with at least one derived character unique to the clade descended from the common ancestor represented by the branch point.

a. Moss
1. Live/preserved specimens
--> Identify gametophyte and sporophyte generation. What domain/kingdom/phylum does this plant belong to?
--> Where does each generation get its food?
Evolutionary relationships of bryophytes, chlorophytes, diatoma, gymnosperms, horsetails, lycophytes, phaenophytes, rhodophytes, angiosperms,lichens,gnetophyta, cyanobacteria, cycadophyta, ferns and pinaphytes.
EVOLUTION CONNECTION The fungus-alga symbiosis thatmakes up a lichen is thought to have evolved multiple timesindependently in different fungal groups. However, lichensfall into three well-defined growth forms (see Figure 31.22).How could you test the following hypotheses? Hypothesis 1:Crustose, foliose, and fruticose lichens each represent amonophyletic group. Hypothesis 2: Each lichen growthform represents convergent evolution by taxonomicallydiverse fungi.

- EVOLUTION CONNECTION The history of life has beenpunctuated by several mass extinctions. For example, theimpact of a meteorite may have wiped out most of thedinosaurs and many forms of marine life at the end of theCretaceous period (see Concept 25.4). Fossils indicate thatplants were less severely affected by this mass extinction.What adaptations may have enabled plants to withstandthis disaster better than animals?arrow_forwardBIOMES & ADAPTIVE RADIATION Adaptive Radiation ven the type of biome these succulent plants are found in, identify 3 important stressors present in their environments.
