Step by step
Solved in 2 steps
- 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.Despite changes in the approach for classifying plants (from artificial-, to natural-, to phylogenetic systems), what has been the common features or structure of these systems that can be attributed to the work- and influence of Linnaeus in the field of taxonomy?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?
- What is the plant variation of: -Mayana flower-Bataw flower-Caballero flower-Dendrobium flowerDescribe the orders Fabales, Rosales and Give the feature based on the characters given in the first column of Table 1. Table 1. Key characteristics of Fabales, Rosales and Brassicales based on the specimens. Character Fabales Rosales Brassicales 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.)What are the two common names of equisetums? What is the appearance of the plants? Their approximate height? Look at Figures 21-21 and 21-24. Equisetums have strobili (in plant identification books, these will be called cones) and canals. Briefly describe the canals and strobili.
- A taxonomist discovers a plant species that is unknown to science. Using your knowledge of the science of taxonomy gained through this course, discuss in a short essay how this taxonomist can go about describing the new species, and what would be important to do during this process. You need to mention: Resources where he/she/they can study the plant and other plant collections, species concepts, taxonomic evidence that can be used and how these can be analysed, type specimens and also nomenclature (what is necessary for him/her/them to publish the name).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.)Why is it important to know the terminologies in plant descriptions?

Scientific name kinds of stem and modifications (if any) presence or absence of lenticel specialized functions Sechium edule Solanum tuberosum Cynodon dactylon Fragaria vesca Psidium guajava Ophiopogon jaburan Bougainvillea Sansevieria zeylanica Allium sativum Cordyline fructicosa Zea mays Bambusa Gladiolus sp. Chlorophytum comosum Ficus sp.What are the Sepals, Petals, and Stamens characteristics of bougainvillea including all the information? Based on the text.Why should the plant specimens be accurately identified/named, labelled, and described?
