Question
Chapter 14.7, Problem 1MC
Summary Introduction
To discuss:
About six plant families, weather they form monophyletic, paraphyletic, or polyphyletic group and also check that extrafloral nectries is an ancestral or a derived character in each of six families.
Concept introduction:
Paraphyletic group is the group of organism that includes an ancestor, but not all of its descendants. Polyphyletic group is a group of organism or other evolving organism that has been grouped together, but does not share an immediate common ancestor.
Monophyletic group is the group of organism that includes an ancestor and all of its descendants.
Extrafloral nectaries nectar is a sugar rich liquid produced by plant in glands called nectaries within the flower, which attracts pollinating animals.

What are trumpet cells in brown algae? What type of cells do they resemble in true plants? Is their presence in brown algae a sign that brown algae are related to the ancestors of true plants, or is it just a remarkable case of convergent evolution?
According to the cladogram in Figure 27-5, which plants evolved first: nonvascular bryophytes, seedless vascular plants, or seed plants?
If the leptoids of mosses were found to contain a protein whose gene had the same nucleotide sequence as the gene that codes for P-protein, would that be significant evidence for either the homology or analogy of leptoids and phloem?

When we look at leafy green moss plants, what are we seeing—the gametophyte or the sporophyte? In a flowering plant species, would the equivalent stage be the plant or the pollen grains and megagametophytes?arrow_forwardPhylogenetic trees are used to show the evolutionary relationships among various biological species and are usually based upon shared derived characters. In constructing phylogenetic trees, it is useful to first draw up a character table to show the presence or absence of characters among the various groups of organisms being studied. a. Draw up a character table based upon the following shared derived characters of land plants: flowers, seeds, vascular tissues, and dependent embryos. Your character table must include the names/descriptions of the plant groups that are being characterized. b. Construct a phylogenetic tree based on this data.arrow_forward
