All topics

• Biology


  The study of living things—literally the science of life
• Domain


  The highest level of taxonomic category that represents the broadest and most inclusive group of organisms
• Three Domains of life

  • Eukarya
  • Bacteria
  • Archaea
• Aspergillus belongs to Eukarya
• With chitin and cellulose in cell wall belongs to Eukarya
• Presence of Nucleus belongs to Eukarya
• Often live in extreme environments belongs to Archaea
• Non-photosynthetic multicellular organisms belong to Eukarya
• Staphylococcus aureus belongs to Bacteria
• Metallosphaera sedula belongs to Archaea
• Photosynthetic multicellular organisms belong to Eukarya
• Escherichia coli belongs to Bacteria
• Methanogens belong to Archaea
• Cell type of archaea

  Prokaryotic cell
• Cell type of bacteria

  Prokaryotic cell
• Cell type of eukarya

  Eukaryotic cell
• These domain/s are single-celled organisms

  Bacteria and Archaea
• These are the one that attaches the branched hydrocarbon chains to glycerol belongs to ether linkages
• These are often live in extreme environments (higher temperatures, lower temperatures and stronger acid concentrations) belongs to Domain Archaea
• Examples of domain archaea

  • methanogens, extreme halophiles, and hyperthermophiles, etc.
• This prokaryotic domain are common in human daily life and can be found almost everywhere belongs to Domain Bacteria
• What does the cell wall of bacteria composed of? peptidoglycan
• Examples of domain bacteria

  • mycoplasmas, cyanobacteria, Gram-positive bacteria and Gram-negative bacteria, etc
• Eukaryotes divided into four kingdoms


  • Protista, Plantae, Animalia, Fungi
• This is in a kingdom of eukarya where you can find most of the unicellular eukaryotes (those whose cells contain a nucleus) as well as the multicellular algae belongs to Protista
• Examples of kingdom Protista


  • slime molds, euglenoids, algae, protozoans
• This kingdom contains photosynthetic multicellular organisms that are terrestrial belongs to Plantae
• Examples of kingdom Plantae


  • mosses, ferns, conifers, and flowering plants
• Organisms in this kingdom are nonphotosynthetic multicellular organisms that digest their food internally belongs to Animalia
• Examples of kingdom Animalia

  • Animals (Vertebrates & Invertebrates)
• This kingdom contains mostly multicellular non-photosynthetic organisms that digest their food externally belongs to Fungi
• Examples of kingdom Fungi


  • mushrooms, sac fungi, club fungi, yeasts and molds
• Are viruses prokaryotes or eukaryotes? viruses are non-living they are neither prokaryotes or eukaryotes
• Fundamental properties shared by all living things

  • Cellular organization, Growth, Development, and Reproduction, Energy utilization and Metabolism, Homeostasis & Adaptation, Heredity, Responsiveness
• How many cells do all living things composed of? one or more cells
• Do all simple or complex cells can be able to grow and reproduce? Yes
• Do all living things use energy? Yes
• How do plants and algae capture sunlight in which light energy is converted to chemical energy in the form of sugar? Photosynthesis
• Where do Humans get energy? From plants and plant-eating animals
• Metabolism


  The chemical reactions in the body's cells that change food into energy or it refers to the sum of all chemical reactions that occur within a living organism to maintain life
