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.
