 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 ...

  CLASS ELEVEN BIOLOGY CHAPTER 2 BIOLOGICAL CLASSIFICATION QUESTIONNAIRE FOR TESTS AND REVISION. PART 7 1.      What are lichens, and what is their ecological significance? a.       Lichens are symbiotic associations between algae (phycobiont) and fungi (mycobiont). They are important indicators of air quality and pollution levels. 2.      How do lichens demonstrate mutualism? a.       Lichens demonstrate mutualism by the algae providing food through photosynthesis, while the fungi provide shelter and absorb mineral nutrients and water for both organisms. 3.      Why are lichens used as pollution indicators? a.       Lichens are sensitive to air pollution and do not grow in polluted areas, making them valuable indicators of environmental health and air quality. 4.      What roles do algae and fungi play in the lichen ...

   CLASS ELEVEN BIOLOGY CHAPTER 2 BIOLOGICAL CLASSIFICATION QUESTIONNAIRE FOR TESTS AND REVISION. PART 6 It can be used as reference material for competitive exams also. 1.      Which kingdom is characterized by heterotrophic eukaryotic organisms with multicellular cells lacking cell walls? a. This kingdom is Animalia. 2.      How do animals obtain their food, and what is their mode of nutrition? a. Animals obtain their food through ingestion, and their mode of nutrition is holozoic, meaning they ingest solid food and digest it internally. 3.      How do animals store their food reserves? a. Animals store food reserves as glycogen or fat, which serve as energy reserves for metabolic activities. 4.      Describe the growth pattern of animals. a. Animals follow a definite growth pattern from juvenile stages to adults, where they attain a specific shape and size characteristic of their species. 5. ...
