 CHAPTER 3 PLANT KINGDOM Questionnaire Introduction to Plant Kingdom Q : What are the primary characteristics of Kingdom Plantae? A : Kingdom Plantae includes eukaryotic, chlorophyll-containing organisms that are primarily autotrophic and use photosynthesis to obtain energy. Q : What does alternation of generations mean in plants? A : Alternation of generations refers to the life cycle in plants where there is a regular alternation between two distinct forms: the haploid gametophyte and the diploid sporophyte Classification Systems Q : What is an artificial classification system? A : An artificial classification system is based on superficial morphological characteristics like habit, color, and leaf shape, rather than evolutionary relationships. Q : Give an example of an artificial classification system. A : Linnaeus's classification system is an example of an artificial classification system. Q : What is the natural classification system? A : The natural classification system cons...

  Chapter 3: Plant Kingdom Introduction Classification of Kingdom Plantae : Kingdom Plantae includes all eukaryotic chlorophyll-containing organisms commonly known as plants. Primarily, they are autotrophic and use photosynthesis to obtain energy. They exhibit alternation of generations with distinct gametophytic and sporophytic stages. Classification Systems Artificial Classification System : Based on superficial, morphological characteristics like habit, color, and number of leaves. Example: Linnaeus's classification. Natural Classification System : Considers natural affinities and includes various internal features like anatomy, embryology, and phytochemistry. Example: Bentham and Hooker’s classification of flowering plants. Phylogenetic Classification System : Based on evolutionary relationships, aiming to classify plants based on common ancestry. Modern classifications use phylogenetic data from multiple sources, including cytotaxonomy (cell features), chemotaxonomy (chemical ...
