5 kingdoms of life

• The three domains of eukaryotic cells include Archaea, Bacteria, and Eukaryota.
• 5domains of life

  Monera, protists, plants fungi, animals
• Eukaryotes have membrane-bound organelles, including the nucleus, mitochondria, chloroplasts (in plants), endoplasmic reticulum, Golgi apparatus, lysosomes, ribosomes, cytoskeleton, vacuoles, and cell wall (in fungi).
• Eukaryota is the domain containing all organisms with true nuclei (eukaryotic) cells, including protists, fungi, plants, and animals.
• Protists are single-celled eukaryotic organisms that can be unicellular or multicellular, autotrophic or heterotrophic, and motile or sessile.
• Animals are multicellular eukaryotic organisms that consume other organisms to obtain energy and nutrients. They have complex nervous systems, sense organs, digestive tracts, circulatory systems, reproductive systems, and respiratory systems.
• Plants are mostly immobile, multicellular eukaryotic organisms that use photosynthesis to produce their own food from sunlight, water, carbon dioxide, and minerals. They have specialized tissues such as roots, stems, leaves, flowers, fruits, seeds, and pollen grains.
• Fungi are mostly nonmotile, multicellular eukaryotic organisms that absorb nutrients by secreting enzymes into their environment. They have cell walls made of chitin instead of cellulose like plant cell walls.
• Plants are multicellular eukaryotic organisms characterized by photosynthesis, cellulose cell walls, and specialized tissues such as roots, stems, leaves, flowers, fruits, seeds, and pollen grains.
• Archaea are also prokaryotic microorganisms but differ from bacteria in terms of genetic makeup and metabolic processes. They inhabit extreme environments like hot springs, salt flats, acidic bogs, and deep sea hydrothermal vents.
• Fungi are eukaryotic organisms that lack chlorophyll and obtain nutrients through absorption rather than photosynthesis. They reproduce sexually and asexually, form mycelium networks, and produce spores.
• Protists include single-celled eukaryotes like algae (which perform photosynthesis) and protozoa (which feed on other cells).
• Some fungi are decomposers, breaking down dead organic matter and recycling nutrients back into ecosystems.
• The Kingdom Fungi includes yeasts, molds, mushrooms, rusts, smuts, and lichens.
• Bacteria are the most diverse group of living things on Earth, with over five million species identified so far. They are small, single-celled organisms found everywhere on our planet, including inside us.
• Animals have specialized structures such as skin, muscles, bones, organs, nervous system, circulatory system, digestive system, respiratory system, excretory system, and sensory systems.
