Textbook Question
Chapter 19, Problem 1TS
Recent DNA evidence suggests to some plants taxonomists that the traditional way of classifying flowering plants is not correct, and that flowering plants need to be completely reclassified.
Other botanists disagree, saying it would be chaotic and unwise to disregard the historical classification groups. Argue for and against keeping traditional classification schemes.

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?
Members of the cactus family in North and South America and of the spurge family in Africa are very similar in structure. In both cases the plants live in desert environments. They have a succulent stem that stores water, no leaves (reduces water loss), stems that can perform photosynthesis, and spines that protect the plant from being eaten. The spines are formed from different parts of the plant in the two families. The two plant families are not closely related.
The similarities between the two families is due to ______ which is caused by ________.
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.

- 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).arrow_forwardThis figure identifies lineages as plants, non-vascular plants, vascular plants, seedless vascular plants, and seed plants.
