- Describe the orders Sapindales, Ericales and Give the characteristics based on the characters given in the first column of Table 1. Table 1. Key characteristics of the orders Sapindales, Ericales and Gentianales Character Sapindales Ericales Gentianales 1. Plant habit 2. Plant type (monoecious, or dioecious, etc.) 3. Leaf type 4. Leaf shape 5. Flower characteristic 6. Fruit morphology 7. Seed size/shape 8. Special seed characteristic (if any) 9. Other characteristics (aromatic, etc.)Describe the orders under the paleodicots (Laurales, Magnoliales and Piperales) in terms of plant habit, reproductive type (monoecius/dioecius), leaf type, leaf shape, floral characteristics, fruit morphology, seed size/shape, and other distinct feature.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. Why is it so?
- Now you will practice identifying the phylogenetic tree that corresponds to a given character table. The following table shows three key events in the evolution of plants: the development of vascular tissue, the development of flowers, and the development of seeds. Plant groups Vascular Tissue Flowers Seeds Gymnosperms 1 0 1 Mosses 0 0 0 Ferns 1 0 0 Angiosperms 1 1 1 Select the phylogenetic tree that correctly represents the data in the character table.Describe the orders Laurales (Lauraceae), Magnoliales (Magnoliaceae, Annonaceae), and Piperales (Piperaceae) by completing Table Table 1. Key characteristics of Laurales, Magnoliales and Piperales based on the specimens. Character Laurales Magnoliales Piperales 1. Plant habit 2. Plant type (monoecious, or dioecious, etc.) 3. Leaf type 4. Leaf shape 5. Flower characteristic 6. Fruit morphology 7. Seed size/shape 8. Special seed characteristic (if any) 9. Other characteristics (aromatic, etc.)The Apiaceae is closely related to the Araliaceae, the family to which ginseng and octopus tree belong. Know the characters which the two families share in List down features of Asteraceae that are considered advanced relative to other dicotyledonous families.
