Six kingdom of life

Living organisms are classified into six kingdoms, with Eubacteria, Plants, and Protists showcasing diverse characteristics. Eubacteria are unicellular prokaryotes found everywhere except extreme environments.

Six kingdom of life

Six kingdom of life

Eubacteria

Bacteria, cyanobacteria (blue-green algae), and actinobacteria
Depending on species, nutrition intake may occur through absorption, photosynthesis, or chemosynthesis
Asexual
Depending on species, oxygen may be toxic, tolerated, or needed for metabolism
some motile
fix nitrogen decomposers
peptidoglycan
Bacteria
Live Everywhere, EXCEPT extreme environments, including in human. Harmful and beneficial

Protists

Amoebae, green algae, brown algae, diatoms, euglena, and slime molds
Depending on species, nutrition intake may occur through absorption, photosynthesis, or ingestion
Mostly asexual, but meiosis occurs in some species
motile/nonmotile
algae major aquatic oxygen & food producers algal bloom
pectin or none (green algae: cellulose)
Unicellular and Multi cellular All Eukaryote (Complex with nucleus and organelles)
Odds and ends kingdom members are different

Plants

trees flowers grass
autotroph
sexual/asexual
physical and chemical events of photosynthesis, respiration, and the synthesis and degradation of organic compounds
major oxygen & food source (photosynthesis - trophic level 1)
cellulose
Multicellular consists of complex cells. Eukaryote

Photosynthesis 12 major groups or Phyla Classified by tissue, seed and stature

Archaebacteria

Methanogens, halophiles, thermophiles, and psychrophiles
Depending on species, nutrition intake may occur through absorption, non-photosynthetic photophosphorylation, or chemosynthesis
Asexual reproduction by binary fission, budding, or fragmentation
Depending on species, oxygen, hydrogen, carbon dioxide, sulfur, or sulfide may be needed for metabolism
nonmotile
contains uncommon lipids
Unicellular Prokaryotes (simple cells no nucleus)
Archaea
Extreme salty water, sewer, acid, thermal Microspcopic 3.5 billion years old No oxygen

Fungi

Mushrooms, yeast, and molds
Absorption
Sexual or asexual through spore formation
most nonmotile
decomposers
chitin
Unicellular (yeast only) Rest are multicellular All Eukaryote
Fungi 'eat' by releasing enzymes to break down nutrients then absorb. Fungi always live in and on their food.

Animals

Example
Mammals, amphibians, sponges, insects, worms
Nutrition
Ingestion
Reproduction
Sexual reproduction occurs in most and asexual reproduction in some
Metabolism
Oxygen is needed for metabolism
Motility
motile
Ecological Importance
human impact on environment
Cell Wall
none
Cell Type
Multicellular Eukaryote
Domain
Eukarya
Description
Oxygen Grow Reproduce Over 2 million species
