- Put the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forwardMonilophytes and seed plants both have megaphylls, as well as other traits not found in lycophytes. Explain this observation using the Figure in the picture and the concept of descent with modification.arrow_forwardIn most plants the largest, longest-lived body is a diploid sporophyte. By one hypothesis, diploid dominance was favored because it allowed a greater level of genetic diversity. Suppose that a recessive mutation arises. It is mildly disadvantageous now, but it will be useful in some future environment. Explain why such a mutation would be more likely to persist in a fern than in a moss.arrow_forward

Seeds Which of these will most likely happen when bryophyte spores are dispersed to a favorable habitat, such as a moist soil or tree bark? a. They will germinate and grow into sporophytes. b. They will germinate and grow into haplophytes. c. They will germinate and grow into chlorophytes. d. They will germinate and grow into gametophytes. Which of the following is the purpose of having cuticles only at the upper surface of thallus of a non-vascular plant like a moss? a. Direct water and nutrient absorption b.
