- Suppose you wanted to make a science fiction film in which human time travelers went back to the carboniferous. What types of modern plants would you use and which would you avoid if you wanted to depict the carboniferous setting as accurately as possible?Which of these best describes the difference between early and more recently evolved land plants? O Early land plants have photosynthetic gametophytes. O Early land plants do not have spores. Recent land plants do not have spores. O Recent land plants use alternation of generations.The plant blue-eyed Mary grows on Vancouver Islandand on the lower mainland of British Columbia. Thepopulations are dimorphic for purple blotches on theleaves—some plants have blotches and others don’t. NearNanaimo, one plant in nature had blotched leaves. Thisplant, which had not yet flowered, was dug up and takento a laboratory, where it was allowed to self. Seeds werecollected and grown into progeny. One randomly selected (but typical) leaf from each of the progeny is shown inthe accompanying illustration.a. Formulate a concise genetic hypothesis to explainthese results. Explain all symbols and show all genotypicclasses (and the genotype of the original plant).
- Green plants differ from the algal Charophycea in: O a. Green plants use phragmoplasts. Ob. Green plants do not have growth throughout the whole length of the stem. O C. Green plants have vascular tissue. d. Green plants have seeds. O e. Green plants do not have asexual reproduction.

Put another way, how could you test thishypothesis?
- Animal cells have neither cell walls nor chloro-plasts, whereas plant cells have both. Fungal cells aresomewhere in between; they have cell walls but lack chlo-roplasts. Are fungal cells more likely to be animal cells thatgained the ability to make cell walls, or plant cells that losttheir chloroplasts? This question represented a difficultissue for early investigators who sought to assign evolu-tionary relationships based solely on cell characteristicsand morphology. How do you suppose that this questionwas eventually decided?The extinct plant Rhynia is important because: Select one:a. they are the only known lineage of land plant to lack a cuticleb. they are some of the earliest evidence of the evolution of lignified xylemc. they occured in huge numbers and formed the coal deposits human use todayd. it is the earliest known Hornwort fossile. it shows the earliest evidence of secondary thickening in land plantsExplain when land plants evolved and the earliest evidence forthese plants.
