- The evolutionary relationships among the major groups of seed plants are uncertain. The cladogram below is one possible representation of these relationships. Which of the following can be inferred from this cladogram of the seed plants? eudicots monocots other angiosperms angiosperms water lities Amborella conifers gnetophytes gymnosperms cycads early seed plants girikgo /You have been hired as research assistant to investigate the origins of the angiosperms, specifically the boundary between a gymnosperm and an angiosperm. Which characteristics would you use to clearly define a new fossil as a gymnosperm? An angiosperm?a. How are the angiosperms classified according to the Angiosperm Phylogeny Group (APG)? b. What is the present understanding about the origin of flowering plants, and the classification of angiosperms into “monocots” and “dicots”, based on most recent evidences? c. The work of plant taxonomists of the 20th century who identified /established the different families of flowering plants based mainly on morphological and anatomical details is still valued and being used today, despite the general acceptance of the Angiosperm Phylogeny Group (APG) as a classification system for the flowering plants. Explain why.
- What are the four modern-day groups of gymnosperms?Which of the following traits characterizes gymnosperms? a. The plants carry exposed seeds on modified leaves. b. Reproductive structures are located in a flower. c. After fertilization, the ovary thickens and forms a fruit. d. The gametophyte is longest phase of the life cycle.Most of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.
- Which of the following statements best compares the two dominant lineages of modern angiosperms? -Monocots are monophyletic whereas eudicots have multiple origins. -Monocots have only one pistil per flower whereas eudicots have three. -Monocots have only one cotyledon whereas eudicots have two. -Monocots are lycophylls whereas eudicots are euphylls. -Monocots have only one stamen per flower whereas eudicots have six.1) Read the following paragraph carefully. There are several mistakes within the paragraph. The ancestors of seed plants are thought to have been heterosporous. In modern day gymnosperms, megasporangia produce the gametes that give rise to the male gametophyte. Gymnosperm and angiosperm megasporangia have one integument layer. The megasporangia is haploid and makes the megaspore. a) How many mistakes are in the above paragraph? b) Rewrite the paragraph to be correct. Underline any changes you make to correct the statements.Which statement below is correct regarding the formation of the endosperm in angiosperms? O the endosperm is formed from the female gametophyte and is haploid O a single sperm nucleus fertilizes the egg nucleus to become the diploid zygote O a sperm nucleus forms both the zygote and the endosperm through double fertilization O a second sperm nucleus fuses with the two polar nuclei of the egg sac МacВook Pro G Search or type URL @ 2# $ & * 2 3 4 6 8 W E R Y

Do you think it helped the angiosperms to colonize the land?After following the life cycle of an unknown plant species, you determine it's life cycle in the following order: sporophyte -> meiosis -> gametophyte -> gametes -> double fertilization -> diploid zygote.
