Chapter 22, Problem 2CT
Summary Introduction
To explain: The reason behind the recessive mutation would be more likely to persist in a plant with a sporophyte-dominated life cycle, such as a fern, than in a moss.
Introduction: The plants are multicellular, photosynthetic eukaryotes on land. They are close to green algae, as they have cellulosic cell walls, chloroplasts, and store starch. They have alternation of generations, that is, a haploid generation (gametophyte) alternates with a diploid generation (sporophyte). Double fertilization is the process of formation of a zygote and the endosperm in flowering plants. It occurs when a pollen tube releases two sperm cells in the ovule. One sperm cell fuses with the egg cell to form an embryo and the other sperm cell fuses with two polar bodies to form an endosperm.

While conducting a plant diversity survey in a temperate rainforest in Washington state, you come across a number of individuals of a low-lying plant species. These plants spread over the surface of moist groun and have numerous small stems that have tiny leaflets. They have root-like structures but do NOT have roots. Back at the lab, tests indicate that the majority of the plant material is haploid. The plant you discovered is likely most closely related to
-a moss.
-complex streptophyte algae.
-a daisy
-a conifer
-a lycophyte
Which of the following pairs of plant structure has the haploid number ofchromosomes?
A. Megaspore mother cell and antipodal cells
B. Egg cell and antipodal cells
C. Egg cell and endosperms
D. Microspore mother cell and antipodal cells
Which of the following is a universal feature of the life cycles of land plants?
Genetically identical gametophyte and sporophyte stages
Multicellular haploid and diploid gametes
Morphologically identical gametophyte and sporophyte stages
Alteration of generations between haploid gametophytes and diploid sporophytes

- There is an evolutionary trend for more basal plants to be gametophyte dominant, but more derived plants to be sporophyte dominant. Suggest one reason why there might have been an evolutionary advantage to spending more time in the sporophyte generation.arrow_forwardWhat is the evolutionary trend in the alternation of generation in plants? Elaborate on adaptive advantages of this trend.arrow_forwardDo mosses have an alternation of isomorphic or heteromorphic generations? That is, can you easily tell a moss gametophyte from a moss sporophyte? When we look at leafy green moss plants, what are we seeing—the gametophyte or the sporophyte?

- PLEASE ANSWER NUMBER 1,2,3, and 4 QUESTIONS: (with brief explanation only) 1. A difference between seedless vascular plants and plants with seeds is that? A. the gametophyte generation is conspicuous in the seedless plants, whereas the sporophyte is dominant in the seeded plants. B. the spore is the agent of dispersal in the first, whereas the seed functions in dispersal in the second. C. the gametophyte is photoautotrophic in seedless plants but dependent on the sporophyte generation in the other group. D. the embryo is unprotected in the seedless plants but retained within the female reproductive structure in the other group. 2. Biologist hypothesize that the first land plants had a low, sprawling growth habitat. Which of the following is part of the logic behind that theory? A. The low sprawling growth gave them greater surface area exposed to light for photosynthesis. B.

- 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_forwardSeeds and pollen grains are key adaptations for life on land. These adaptations relate to reproductive success and survival advantages. The following questions require you to explain some of these adaptations. A. Contrast sperm delivery in seedless plants with sperm delivery in seed plants. (5-6 sentence) B. Discuss at least one feature of seed plants that contributed to their success on land in contrast with seedless plants. (2-3 sentences) C. Flowering plants (Magnoliophyta) are the most successful of all plant groups in terms of their species diversity and ubiquity across habitat types. Climate warming is causing shifts in the timing of life history events for many species. Discuss how climate warming may influence reproductive strategies employed by flowering plants. (2-3 sentence)arrow_forwardCucumbers and melons are both members of the genus Cucumis, which includes members with distinct geographical origins: the Asiatic group and the African group. The African members of the genus possess disease resistance not found among the Asiatic members of the same genus, and scientists were interested in creating melon-cucumber hybrids that would possess enhanced resistance to mildew and plant viruses. Plant breeders have nicknamed this new fruit, the “melumber”, but its scientific name is Cucumis hytivus. Please fill in the table attached and answer the following questions. a.) Assuming that the Hoosier cucumber was produced in a laboratory at Indiana University, briefly describe the most likely method by which it was produced and the biological mechanism involved in the action of the agent utilized by the scientists. b.) Suppose scientists wanted to employ an alternative approach to producing cucumber plants that were resistant to the cucumber mosaic virus. List the steps…arrow_forward
