At severаl pоints in the cоurse, we discussed twо feаtures of mаny land plants: pollen and seeds. We also talked about four groups of terrestrial plants: nonvascular plants, seedless vascular plants, gymnosperms, and angiosperms. Which groups of plants have pollen? How does pollen help plants complete their life cycle in a dry terrestrial environment? Which groups of plants have cuticle? How is cuticle beneficial in a dry terrestrial environment? Can pollen, seeds, or both disperse to form new populations? Briefly explain your reasoning. If a plant population experiences dispersal to a new location that is geographically isolated from the original population, how could that result in speciation - the divergence of the two populations into separate species?
